RackChoice 4U Rackmount Server Chassis - Fits 360mm AIO Radiators

Our review of the RackChoice 4U rackmount server chassis finds it best suited for small lab racks and compact server deployments that need room for liquid cooling. The single biggest reason to buy is its support for elevated 360mm liquid cooling radiators, which lets builders run efficient AIO cooling in a 4U profile without resorting to larger, heavier enclosures. It is a straightforward, utilitarian chassis: well built, roomy for drives and expansion cards, and intended for rack shelves rather than sliding rails.

Key Features

• 360mm radiator support: Allows installation of an elevated 360mm liquid cooling radiator for improved thermal performance in a shallow 4U space.
• Wide motherboard compatibility: Fits EATX, ATX, MicroATX, and Mini-ITX boards so it works with a broad range of server and workstation motherboards.
• Drive capacity: Two internal 3.5 in drive bays provide a simple, direct option for bulk storage without occupying expansion slots.
• Full-height expansion: Eight full-height PCI/PCIe slots let you install multiple add-in cards such as RAID controllers or GPUs where supported by the motherboard.
• Compact footprint: Overall dimensions of 438mm x 178mm x 465mm keep the chassis compact for dense rack layouts while still providing internal room.

Who It's For

This chassis is aimed at system builders and IT hobbyists who need a compact 4U rackmount case that can accept an AIO or custom elevated radiator up to 360mm. It suits small servers, test benches, and home lab setups where liquid cooling compatibility and multiple expansion slots are priorities.

It is not ideal for users who require sliding rails or built-in rail hardware; because sliding rails are not supported, installers should plan to mount the chassis on a rack shelf or fixed support. Also, those needing large internal drive cages or hot-swap bays should look to larger rack chassis with more drive capacity.

Pros & Cons

Pros

• Sturdy build quality that customers describe as reliable for rack use.
• Roomy internal layout that accommodates an elevated 360mm radiator and long cards.
• Broad motherboard support from EATX down to Mini-ITX for flexible builds.
• Eight full-height expansion slots for multiple add-in cards.

Cons

• Does not support sliding rails, so it requires a rack shelf or fixed mounting.
• Only two internal 3.5 in drive bays, which limits internal storage expandability for large arrays.
