Form factor and target workload

The ASUS RS300-E11-WOCPU011Z is a 1U rackmount barebone server designed for general purpose workloads. It arrives without a CPU or memory installed, allowing integrators to select components that match their specific performance and budget requirements.

Who this suits and who should look elsewhere

System builders who need a compact chassis with four hot-swap 3.5-inch drive bays and redundant power will find the platform a direct fit. Buyers who require more than one processor socket, additional expansion slots beyond the three provided, or integrated graphics beyond a single HDMI output should consider a different form factor.

Deciding specification

The Intel C252 chipset and LGA 1200 socket limit the system to a single Xeon E-2300 processor with a 95W thermal envelope, dual-channel DDR4 3200/2933/2666 UDIMM memory up to 128GB, and PCI Express 4.0 lanes on the primary slots.

Questions about this item

What rack depth and clearance does the 1U chassis with 19.56" × 17.30" dimensions need?

The server is 19.56 inches deep and 17.30 inches wide, so the rack must provide at least that depth plus cable bend radius at the rear and front door clearance for the hot-swap drive carriers.

Which PCIe slot should be populated first when adding a full-height GPU and a RAID controller?

Install the GPU in the PCIe 4.0 x16 full-height slot; if the x8 half-height slot is also used, the x16 link drops to x8, so plan card placement before tightening the riser screws.

How often should the dual 450W 80+ Platinum power supplies and hot-swap backplane be checked?

Inspect both PSU status LEDs and listen for fan-speed changes during each scheduled maintenance window; the backplane has no moving parts but verify drive-carrier latch springs annually.
