## Description

SilverStone’s RM21-308 is a high performance storage server chassis designed for the professional storage environment. It is equipped with hard drive trays compatible with 2.5" or 3.5" drives and has fan assembly with motherboard support for up to Micro ATX form factor. There are also flexible mounts to accommodate most 2U single/ 2U redundant server, PS2 (ATX) power supplies. RM21-308 also has ergonomic, tool-less rail* designs for easy rackmount integration. With an overall package designed for maximizing efficiency, flexibility, and durability, the RM21-308 is a great choice for professionals or data center engineers looking to build a storage server.

Review: Compact Powerhouse for the Home Lab - The SilverStone SST-RM21-308 is an exceptional 2U rackmount case that perfectly bridges the gap between professional-grade storage and consumer-friendly hardware. Built from solid metal with a premium finish, this short-depth chassis delivers remarkable flexibility for home lab and small server setups, supporting up to eight 2.5" or 3.5" SAS/SATA drives through dual Mini-SAS SFF-8087 connectors. It’s impressively well-designed for its compact size, accommodating Micro ATX motherboards and standard ATX power supplies without the need for specialised enterprise gear. The included three 80mm PWM fans provide efficient airflow across all drive bays, keeping components comfortably cool even under sustained load. The construction quality is superb, with a rigid frame and tool-less drive trays that feel far sturdier than most consumer-level cases. Despite its dense layout, cable management is surprisingly straightforward, and the independent drive status LEDs are a thoughtful touch for quick diagnostics. Delivery took just under three weeks—earlier than the expected month-long lead time—and it arrived exceptionally well packaged. Once built, the case has proven whisper-quiet for a rack unit, housing a Plex server and supporting hardware without a hint of strain. Everything fits perfectly and runs reliably, making it a true gem for enthusiasts who want enterprise-class organisation without the data centre noise or cost. 5/5 stars – One of the best purchases of the year. The RM21-308 is a rare find: compact, efficient, and flawlessly suited to home-lab or media-server builds that demand reliability and style in equal measure.
Review: 4ポストラックに2Uのラックサーバを取り付けようと思って購入．ですが，ちょっと短い．説明書には「2cm伸びる」とは書いてありましたが，その部分はリベットで固定されていて絶対に動きません．その分，☆を一つ減らしました． その代わりなのか，ラックにネジ止めする「エクステンダー」が4個付いていまして，そのうちの2個を使って伸ばして解決しました． それがなければ，ラックへの取り付けは比較的簡単（道具は要らない）です．DELLやHPのレールほどじゃないですけれども．

Associé à un boitier de la même marque, le montage sans outils se fait en un temps record. Le kit semble de plus de très bonne qualité.
