HOTCFWQ 4U GPU Server Chassis Air-Cooled 438x480x177mm 12x13in MB 4xU.2 3x120mm Fan ATX/CRPS

4U Rackmount Server Chassis

The HOTCFWQ 4U rackmount server chassis is built from 1.0 mm SGCC steel and measures 438 mm wide by 480 mm deep by 177 mm high. It supports motherboards up to 12 by 13 inches and accepts ATX or CRPS power supplies. Four U.2 drive bays accommodate 2.5 or 3.5 inch drives. Three 120 mm fans provide airflow, with optional dual 8038 mm fans on the rear board. Eight vertical PCI expansion slots and two front USB 2.0 ports complete the package. The design follows EMC guidelines to limit electromagnetic interference.

GPU Compute Hosts and Storage Nodes

This chassis suits builders who need a 4U enclosure for AI, deep learning, rendering or GPU computing workloads with front-accessible U.2 storage and plenty of PCIe space. It is not for teams that require more than four U.2 bays, need support for larger E-ATX boards beyond 12 by 13 inches, or want a tower form factor instead of rackmount. Buyers who need integrated redundant power supplies or liquid-cooling infrastructure should look at other platforms.

Four U.2 Drive Bays with 2.5 and 3.5 Inch

The four front-accessible U.2 bays accept both 2.5 and 3.5 inch drives, letting you populate high-speed solid-state storage or high-capacity hard drives in the same slots. This single specification decides whether the chassis matches your storage density and drive-type requirements.
