Silverstone Technology RM52 5U Rackmount Server Chassis with Dual 360mm Liquid Cooling Capability, SST-RM52

Great upgrade 4U case for my home lab cloud server. I needed more room to add a RTX-5090 to this rig, and didn't want to go all the way to a 5U case. To be clear, there is only one 5090 card brand (Zotac) that will fit this 4U case with enough room on top to comfortably fit the 600W connector & wiring. If using another brand, I would probably go with a 5u case. I installed the Zotac Solid OC specifically in this build. Other Zotac models will likely fit as well. The SOLIDs 137mm height is a perfect fit for this case (which specifies a154mm max height). The case came with a number of front GPU support brackets. I used one, and it makes for a very solid mount. The 5090s aluminum frame holes at the front of the card lined up perfectly with the holes in the provided bracket. With the card secured with three screws in the back, and the case bracket in the front, I am confident the card will not come loose when removing/installing this case in my rack. As far as cooling, the case will fit one Noctua NF-A14x25r G2 PWM (140mm) and two NF-A12x25 PWM (120mm) in the front panel. It is tight, but can be done. Use the adjustable slots instead of fixed holes to slide the two 120mm fans far to the left and right sides of the case to leave room for the 140mm in the middle. I loaded this case up with a total of 8 fans (added a custom slot bracket with (2) 40mm fans for a total of 7 case fans and a Noctua NH-D12L CPU cooler w/fan). This configuration provides fantastic airflow and dropped the CPU temp by a solid 20C over the previous 2U case which was cooling challenged even with a Ghost S1 CPU cooler and (4) 80mm case fans.. Overall well made case. Even with a 10G NIC card and the RTX 5090 installed, there is still room to access at least 2 of the SATA 2.5" mounting plates comfortably (no wires/cards in the way). I now plan on adding a couple of large SATA drives in raid mirror as a home network file server and for backups, making this machine even more of a Swiss army knife of a server. This combination of fans is almost completely silent, even with a moderate load. With the fans at 100% it is only noticeable if you are in the same room, but I doubt you would hear it in the next room. Overall very happy with this case. One negative ,but not enough to remove a star, the manufacturer does not sell a set of sliding rails that fits this case in short racks (slightly less than 22" deep). This case uses screwless rail studs to connect the rails, and there is no option for screw on rails. The only rails designed for this case are too long for my rack. I ended up using the Cyber Power 4POSTRAIL, which worked, but is VERY tight when sliding in the heavy duty rack ears on this case. Installer trick, don't lock down the rail mounting screws (just hand snug them). After you slide the case in fully (might take some wiggling), lock the back screws and the bottom two screws in front. This will lock the rails in place with perfect spacing/alignment, then you can pull the case out and lock down the top two front screws.

This is a great rack mounted case. You can run single or redundant power supplies, It fit my ATX motherboard and RTX card with plenty of room to spare. I have a 360mm AIO cooling system for my CPU and this case handles it with ease. Airflow is consistent and has a well defined path - front to back. Noise levels vary on system load and environmental temps. Plenty of USB ports in front, though I would have liked to see 2 CD/DVD drive bays. Mounts EASILY into a standard rack. Needs 4 screws. Can be mounted to rails to slide out if you want to go that far, however the rails are not included with the case and must be purchased on their own. If you wanted to put the case on it's side and not mount it in a rack, you can do that also. I can see myself re-using this chassis for multiple system builds.

I've had this in use for a few months now. If you don't have an extreme setup or anything, this will do nicely. My older editing rig that I wanted to test this case out with is listed below. I wasn't sure how this was going to work -- would the airflow be good? Would everything fit? How noisy would a 'basic' server case be (clanking, rattling, etc)? So far, I'm very pleasantly surprised at how simple this change over was. Reading the comments, it made it seem like it would be more trial and error, which I didn't experience anything other than a straight forward drop in. With the rack in my closet, I never realized how quiet my computer room could have been many years prior to this. Wish I did this a long time ago. Way more expensive than going a simple desktop case but well worth it. When editing or gaming in this case, my temps are not any worse than with my high flow desktop cube case I had (Corsair 540). I typically stay ~55-58c during video rendering and during gaming the gpu is ~60c with a mild fan curve. Even in the closet, the stock fan curve was louder than I wanted but kept temps down in the low 50's. So I figured the trade-off of >10c for much quieter sound was worth it. So if you're worried about this case not having all the fans you've become accustomed to with gaming cases, don't fret. A good AIO cooler (the Arctic II is excellent and fits great in this case!) and two Noctua 80mm fans on the rear keep the flow decent with minimal sound. Components i7 6850k (oc'd to 4ghz) x99 Titanium ATX mobo R9 Fury 4 x SSD's Arctic II 240 Cooler I ended up not using the gpu bracket or hdd cage. I just stuffed my 4 ssd's in the area for 5.25 devices since I'll never use that for anything. Cable management is easy but not as much of a requirement for something that will be tucked away. Sure, you still want it clean and easy to work on as well as keeping the restriction of airflow down, with that in mind, it's nothing to get the cables out of the way. The case is solid and sturdy. When put in the rack with the lid, no rattles from the case whatsoever. With the front lockable door open or closed, it made no difference in my temps, so I just keep it closed. Love the usb-c port on the front! Mild cons: It's pricey. Can't find good quality sliding rails to work with it. Will be moving my other 2 computers into these cases over time.

Yes, this case is very expensive, but the beauty of a case is it can live on from one iteration of a server to the next. The 24 drive bays give you plenty of room for future expansion without having to use janky solutions because you are out of space for drives. I will say the choice of SAS backplanes did make it difficult to use a consumer motherboard since most have at most 2 x8 PCIe slots and I was already using an SFP card for 10gig fiber. I had the choice of one very expensive SAS HBA with enough ports for each individual backplane or 2 more common HBAs (LSI9300) with a riser and PCIe bifurcation. Keep this in mind when planning your build. For the record each backplane handles one row of drives (4) and there are 6 total in the 24 bay case. Functionally wise this case checks all the boxes for a sweet home lab rig with lots of storage. Just keep in mind that you will have to do some research and learn a little about server parts to have an optimal experience. One would hope that by the time you are entertaining the idea of a case like this you already have some knowledge under your belt. Also, this thing is super loud so plan on putting it somewhere that doesn’t matter, buying Noctua fans, and/or fan extension cables to hook the fans up to your MB headers instead of the backplanes. The backplanes just run the fans at 100% all the time, which isn’t necessary.

Pros: 1) Only NAS chassis I'm aware of with 12 hot-swappable drive bays + 120mm to 360mm radiator support. Most other chassis either give you a lot of drive bays with limited CPU cooler support, or have a wide range of CPU cooler support, but limited drive bays. 2) Built like a tank. I don't have this in a server rack mount, so its been taking its fair share of beating when I've had to move it around, but its sturdy as hell. Cons: 1) Built like a tank. This thing is heavy even without all 12 bays populated... 2) Very sharp corners and panel edges. I hope SilverStone takes some time to find ways to round off the sharp corners and panel edges. I can see someone cutting themselves when rotating this around for maintenance since its already so heavy. Other Notes: Someone else mentioned that the 3 OEM 80mm x 15mm hard drive fans are noisy. They are. According to the manuals the default fan profile when the fan headers are plugged into the backplane is drive temps >= 45C means 99%-100% fan speed. 12 fully populate bays will mean your drives will be 45C or more, so I wouldn't recommend using the backplane fan headers unless you like your fans always at basically 100% I did try a bunch of different brands of fans to test out, and the OEM fans are probably the best 80mm x 15mm fans to have in terms of noise to cooling capabilities. I tried 3 Noctua NF-A8s (80mm x 25mm) mounted behind the backplane bracket towards the PSU (compared to the OEM fans being mounted in front of the backplane bracket towards the backplanes), and while those were definitely quieter they could not sufficiently cool down twelve 3.5in drives without being on 100% speed (and at that point you can definitely hear them). If you want to mount 80mm fans from other brands in the same orientation as the OEM fans then you can get away with anything up to 80mm x 20mm. Otherwise you can go up to 80mm x 25mm without issues when mounting the fans behind the backplane fan bracket towards the PSU. You can technically go as deep as 80mm x 38mm when mounting the fans behind the backplane fan bracket instead of the default OEM orientation, but you may run into some issues with thread holes from the mobo preventing flush mounting of your fans. I settled on 3 Sanyo Denki 9GA0812P1H611 80mm x 38mm fans (mounted slightly crooked) at 6% - 14% duty cycle. That is sufficient for keeping all 12 drives between 38C and 45C during heavy drive loads while keeping the noise as low as possible.

This RM61-312 6U 12-Bay Rackmount Chassis is rock solid and very heavy, even when its empty. It fit my needs to be able to consoldate two NAS builds I had into ONE NAS server with ample drive space and use my existing ATX mobo, ATX PSU and my 240mm radiator CPU cooler. Once mounted in my rack, it only sticks out about 2", which is much less than a standard rack mount server would. The front upper bay allowed me to install two 5.25" bay hard drive cages (not included with case). It would've fit three but I didn't need a 3rd at this point and used the space to mount a 120mm intake fan. All in, I have 22 spindle 3.5" drives and 4 SSD drives installed. To connect up the 12-bay storage you will need - 3x - SFF-8643 cables (data) - 6x - molex adapters (power) They do include ample screws for just about any configuration imaginable you'd be throwing at this. Cable management was a breeze. The front removable cover does have a thin filter screen on it to block dust intake. Nuances/Annoyances: - On the bottom of the case is a grill to allow the PSU fan output - I had intially planned to have it sit on the bottom of my rack, but instead had to raise it's mounting 1U since my rack is not open bottomed. - I'm not sure if its the dimensions of my 5.25" bay cages, but I had gaps after I mounted the provided 5.25" face plates. They did provide a metal thing, I think, for the left most side, but it didn't fit. There are also the top mounting holes to attach the cages that appeared to be miss-aligned for the left-most bay causing the gap on the left. I ended up 3D designing and printing myself the needed face plates. Which in the end worked out better and made it so I could mount a front intake fan. - The price. Pretty steep. I bit the bullet and went with this one though versus some no-name knock off case because I wanted to ensure the case would be sturdy, not flimsy, with the number of drives it was going to contain. I also wanted piece of mind on the quality components of the HDD back plane. The individual HDD cages seem to be a little bit flimsy. Just be gentle with them. Overall, I'm very pleased with the quality of the case and I'm extemely happy with how the build turned out. This was my first SilverStone case. If I ever decide to build another PC/server, I wouldn't hesitate to get one from them again.

The double-packed box more than withstood the rigors of UPS. There was no damage to the case. The case was more than I expected. The pictures (here and elsewhere) don't do it justice. It is roomy, well built, beefy (not light!) and well finished. The dust filters are not magnetic, but snap in; they should be something that you are careful with. The case isn't a deep monster, but has enough room for a good build. I'm using SAS drives and while the drive connectors extend into the "motherboard area" it hasn't been a problem. That said - I have four 6TB drives. Depending on the number of drives you have and the amount of drive cooling you want, YMMV. I haven't had a chance to resilver an array so I don't know what internal temperatures would be like. But, so far, so good. It will probably take me a couple of weeks to become aquanited with the nuances of the case. The "handles" on the case are sturdy and more than support the weight of the case. I haven't installed rails as my rack hasn't been built yet. The case handles remind me a bit of the old APC UPS units (that kind of sturdy). The case connectors were long enough for my build, but I could see issues with others - depending on motherboard, components and cable routing. In my case everything went together well. There have been complaints about not being able to remove the drive trays or moving parts around but that doesn't seem to be a problem - it may take a few seconds to figure out what to unscrew but it can be done. I don't know if any parts of the clone cases will fit, but I'd be game to try. Overall a nice case. Yeah it was expensive, but I think it was worth it. AND it was in stock. The only nit to pick is the use of the small screws (use a magnetic tipped screwdriver!). I have enough parts to build a second server. If I had the same requirements, I wouldn't hesitate to use the same case. *** UPDATE *** I had to replace hard drives as my sas drive went to the bit dumpster in the sky. I purchased some ironwolf sata drives and found that i can only use two mounting screws to secure the drives. I don't think it is a fault ot teh case, but having deeper hard drive bays would allow for secure mounting of hard drives. And a curse on Seagate for deciding to omit screw holes. So if secure hard drives are your thing... you might want to take that into consideration...

As an enthusiast, I've always wanted to take my gaming and computing experiences to the next level by building a high-end home lab or rack-mounted gaming PC. And that's exactly what I did with the SilverStone Technology RM44 4U Rackmount Server Chassis. **Unparalleled Build Quality**: From the moment I opened the box, I was impressed by the attention to detail and build quality of this chassis. The solid aluminum frame, heavy-duty screws, and precision-cut panels all contribute to a sense of premium craftsmanship that's hard to find in other products at this price point. **Gaming-Grade Cooling**: With its support for up to 360mm AIO liquid coolers or radiators, the RM44 is perfect for high-performance builds that generate a lot of heat. Whether you're building a gaming PC or a home lab server, this chassis has got you covered when it comes to keeping your components running smoothly and efficiently. In short, the SilverStone Technology RM44 4U Rackmount Server Chassis is an absolute must-have for anyone building a high-end home lab server or rack-mounted gaming PC. Its unparalleled build quality, gaming-grade cooling, and premium features make it the perfect choice for enthusiasts who demand the best from their systems. IT CAN ALSO BE USED AS STANDARD DESKTOP TOWER CHASSIS!! EDIT: Lowering star rating to 4 stars. Purchased the 4U 20bay chassis and the quality control is just kinda ehh. Some of the 3.5" drive screws did not have threads, one of the two rail slides do not lock in the pulled out position unless forced by pulling super hard (which is not a smart thing to do when ther eare a bunch of spinning disks in the server), and one of the three hotswappable fans came with the connector upside down and the fans connector was jammed down into it and bent out of place. The hotswap fans also can not be adjusted unless you want to unplug them from the hotswap plugs and plug them into the motherboard instead, removing the ability for them to be hotswappable. They are extremely loud and do not recommend using them in the default configuration if the chassis is going to be in the same room as you, unless your someone who doesn't care about noise.
