ASRock Rack 1U4LW-X570 1U rackmount barebone server 4 hot-swap 3.5" bays AM4 X570

1U rackmount barebone for AMD Ryzen

The ASRock Rack 1U4LW-X570 is a 1U server barebone that accepts AMD Ryzen 5000, 4000 and 3000 Series desktop processors in an AM4 socket. It is built for small-business hosting, web serving or virtualisation clusters where density and ECC memory matter. No CPU, memory or storage is installed, so the integrator chooses every component.

400 W PSU with four hot-swap 3.5" bays

A 400 W 100-240 V power supply is included and the chassis provides four hot-swap 3.5-inch SATA bays plus three fixed 2.5-inch SATA bays. Front I/O offers two USB 3.2 Gen1 Type-A ports. Dual 1 Gigabit Intel I210 LAN and a dedicated IPMI port give separate management and data paths. One full-height half-length PCIe 4.0 x16 slot is available via the RB1UX16_G4 riser.

Two M.2 slots and DDR4 ECC support

The X570 chipset supplies two M-key M.2 sockets (22110, 2280, 2260, 2242) that run at PCIe 4.0 x4 or SATA 6 Gb/s depending on the processor generation. Four 288-pin DDR4 slots accept up to 32 GB ECC or non-ECC UDIMMs each, with speeds up to 3200 MHz on Ryzen 5000 and 3000 Series CPUs. The Aspeed AST2500 provides basic graphics and remote management. This platform replaces older 1U boxes that lack PCIe 4.0 and hot-swap 3.5-inch density; the jump is worth it when you need current Ryzen performance and tool-less drive swaps in a single rack unit.
