Target Builds

The Rosewill RSV-L4620 is a 4U rackmount server chassis built for E-ATX, ATX and Mini-ATX motherboards. It suits multi-GPU rendering, AI training or virtualisation hosts that need up to eight expansion slots and room for long graphics cards. Buyers who need more than two 3.5-inch drive bays or a deeper power-supply cavity should look elsewhere.

Compatibility Check

Verify your motherboard measures no larger than 12 by 13 inches and that your CPU cooler stays within 158 millimetres. Graphics cards must not exceed 330 millimetres and the ATX power supply must fit within 180 millimetres. Front-panel connectivity requires a USB 3.0 header and a USB 3.2 Type-C header on the board.

Build & Connectors

The SGCC steel frame ships in black and silver with three pre-installed 120-millimetre PWM fans in the middle chamber. A 360-millimetre AIO radiator mounts directly for liquid cooling. Front I/O provides one USB 3.0 port and one USB 3.2 Type-C port for 10 gigabit-per-second transfers. LEDs show power, drive activity and dual LAN status.
