Rosewill SRM-01B Black Steel/Plastic Micro ATX Mini Tower Computer Case

As-sold it's 3 stars, barely. With the easy mods below, it gets to 4 stars if you value a small build.This is one of the smallest, narrowest mATX cases you can buy and that's why I bought it, but that comes with compromises.The biggest one is not the cramped space, but the 80mm exhaust fan as you can't fit anything bigger in this small of a case. Want a 120mm exhaust fan? You need to buy a bigger case. I'm using a Ryzen 5 2600 and Sapphire Pulse 5600XT and yes, the Pulse *barely* fits. Maybe 2mm taller and it wouldn't. But the real issue is that close fit means less ventilation and with the stock CPU cooler, both the CPU and GPU head north of 75C while gaming.Both can be "fixed" by just removing the side panel. But that's no fun.Instead the heat/ventilation problems can be actually fixed with a few case mods on the back. First is to cut the case's grill away from the 80mm exhaust fan (thin metal makes this easy) and then run that fan at full speed. It's not loud and now does a very good job removing much of that heat. I also bought a $20 Cryorig M9a for the Ryzen and it both fits in the case and, along with the newly freed case fan, easily keeps the R5 2600 cool. This combo rarely exceeds 60C in games now.The second mod is to remove the lowest PCI bracket. Yeah not much of a mod but this lets the 120mm front case fan blow over your GPU and exhaust some of that heat out the back. Even with the cramped airflow of the bulky Pulse, it doesn't go above 66C or so when gaming at 100% GPU use. Of course the Pulse's size is also helping here as it's an overkill cooling solution for the 5600XT.I have zero complaints about cooling an hours long gaming session in this case now.Other notes:Case is very cheap, treat is carefully as metal is thin.Lift the front of the case with longer feet or risers as the small front air intake is at the bottom.You need to remove the 80mm fan to install your motherboard.Front IO is better than many in this price range.Cable management doesn't leave a lot of room, use a semi-modular PSU and you can get a clean looking install. I found that to be a fun challenge but others might find this annoying.That cable management is likely very important to keep the airflow controlled, especially for the GPU. My air across the bottom of the case is completely unobstructed.If you build a similar setup to mine with an aftermarket tower cooler, things have to be installed in the case in this order or you could block your GPU out:1. Motherboard with CPU cooler mounting backplate already installed2. 80mm case exhaust fan3. GPU (if it's big like the Pulse, even medium size ones like a Ventus 1660 Super might still need to go in here)4. Mount the CPU cooler5. Everything elseI used the R5 2600's box cooler for a while and there is *barely* enough clearance to install/remove the Pulse when everything is installed. The Cryorig takes up way more space and traps the GPU in (or out if you didn't install it first).So I can't remove my GPU to upgrade it unless I either remove the CPU cooler or cut part of the side support of the case away. Seeing as it's a pretty flimsy case, cutting this may not be the best ideal. The Cryorig is at least easy to mount so just removing and reattaching the cooler might be best.In conclusion, I actually had fun working with this case's limitations and in fact I'm very happy with how it finally turned out.

Let start that I'm near 70 years old now . And retired for over 12 years also . So with that said you should understand that every thing I do , I try to do the cheapest that is acceptable for my needs .You may ask why a old man is building his on desktop instead of buying a new store bought one !The reason is I've bought a lot of store bought one's over the years for my children and myself and they always turned into problems after 3 or 4 years and were hard to find parts to fix them , so about 8 years ago I built my own computer and this computer has and is still is working fine . But its starting to get a little slow on the video side of things and that is largely what I use this computer for ( youtube , online movie rentals and so forth )I do not have Cable TV because it's a waste of money for me . I have a in house ant. that I can get over 20 channels on and that's plenty for me .The build that I'm now using are as follows .Parts from Tiger Direct ,year 2014Systemax OEM Micro ATX computer case tower w/300W power supply = $ 16.78Asus A55M-E FM2 mother board = $ 58.53AMD A4-4000 Dual-core APU = $44.66SAPPHIRE Radeon HD 5450 Graphic card - 1GB DDR3 =$34.99That's about $175.00 in those parts . I do not remember what the 1-Tereabit Hard drive or what windows cost at that time but was probably about $180.00 to $220.00 for both items .I did not need to buy things I already had , monitor , keyboard , printer and things like that .So as you can see that was a pretty cheap build for that time and is still working fine except for slow loading vids .sometimes .I looked at if it made any sense to update these parts or build a new computer and decided to build 2 computers1 with all new parts and 1 with my old disk hard drive and CD player and whatever else can be used from the old to a new in a new case . In time as the new computer is up and running well I will get a SSD to transfer data from old disk drive to as they are getting much cheaper than when I did my first build .So on to the new build . I've watched many YTUBE vids about building your own computer and what cases and parts they think you should use . Almost all these vids are for gamers . But they can be helpful in deciding what parts to use in a new build .After all that I decided to order the fowling things to make sure they go together well . Rosewill R521-M Case with 400W power supply built in for about $55.00 from Amazon . ASRock B450M pro4 motherboard about $65.00 from Newegg computer parts .AMD RYZEN 3 1200 CPU from AmazonCrucial 4GB DDR4-3200 UDIMM 288 pin ( 4 of these ) from AmazonLogitech Z313 50 W speakers from Amazon500GB SSD from Amazon and adapter rail from AmazonThe Rosewill and the ASRock mother board fit well together and had all of the standoffs and screws needed .The problem with the case is the wiring to the mother board is 4 pin to the ATX but the mother board wants 8 pins . I wonderd what to do about this problem so I read many reviews on this site until I read one that said all I need to do was buy a 4 pin to 8 pin adapter , sorry to say I did not click this was helpful button because I quicklywent to Amazon to see if they had 4 to 8 adapter and they did so I ordurd 2 of these and also orderd the last Rosewill case they had of this type for my second build to up date old computer later on .I hope this review helps somebody like the review about the 4 to 8 adapter helped me .Good luck on your build .John

This case if perfect for a budget sub £500 build where every penny counts. At just £25.99, the SRM-01 looks nice and sleek without spending too much money. The aesthetic is clean and modern, while the build quality feels a little plastic to me, but for the price, this case looks great.The case has a top mount PSU area with room for up to an Micro ATX motherboard. The case has good airflow too, but the position of the GPU (At the very bottom) means that some blower style GPUs that pump out heat may struggle for air. Cable management is left down to a few rivets dotted about the case, with a sub 1cm gap behind the motherboard. I would love to see some more rivets and possibly a deeper gap behind the motherboard.The design of the HDD and SSD mounting system is rather odd however - A swing out door from within the case acts as a mounting bracket which at times is fiddly to use properly. Also, if you mount a HDD on the bottom of the two mounting spots closest to the GPU, you wont be able to install a long or tall GPU. I have had to mount my HDD to the top mounting spot and stick my SSD to the side with some velcro. Not ideal.Luckily, the GPUs I have used in this case all fit due to their small length of about 17cm. Be careful when you buy a GPU and ensure that it will fit in the case. Longer GPUs will fit, but only if their height is small enough to lie underneath the HDD door when closed. (See image). When I have built in this case, I often felt as though I was cramming everything into the case, but at the end of the build everything was firmly attached and well organised.But really, If you are buying a system which is £500+ I would totally recommend buying a higher end case - after all the case is were all the components are held and it is what you will see every time you use the PC. This case is perfect for someone who needs to scrimp every penny and doesn't mind working harder to make everything fit. But the moment your build exceeds £500, then I would recommend the  NZXT S340  - at double the price its certainly not a budget case, but it ticks every box when it comes to airflow, compatibility and aesthetic.-----PROS------ Clean Aesthetic- Small Form Factor- Super Budget Price- Perfect case for Sub £500----CONS----- Must check compatibility for GPU height and length- Bendy Plastic in some areas- Airflow is limited for larger GPUs- Strange and sometimes awkward HDD bracket----IMPROVEMENTS----- A dedicated HDD tray area- More GPU clearance- Less PlasticTo Conclude, this case is excellent for the price, but bear in mind that you always get what you pay for meaning this case is not suitable for higher end builds with larger GPUs and more 'stuff'. If you count your pennies like myself then we have a winner. I would recommend it.BUT, If you can afford a better case, then buy a better case. If that makes any sense... NZXT S340

Cheap and (if it was a sentient being) cheerful. I replaced the supplied fan with something bigger and quieter. People talk about flimsy. What do they do? Use it as a step?

Revived my old lenovo 😂 it had i5 2320 and 8gb ram so just moved it to new case XD added new gpu and psu... also case is easy to work with 5* from me

Nice looking case with one vast problem, the heat from the provided power supply is exhausted into the case which in turn overheats everything else, well made solid case but requires a lot of modding to be viable.

Good
