AsRock 2U4G-C621WS 2U Rackmount Server Barebone

The AsRock 2U4G-C621WS is a 2U rack-mount server barebone built around AsRock's C621WS platform for dual Intel Xeon Scalable processor deployments. It ships as a bare chassis-and-board platform, giving system integrators control over CPU, memory, storage, and card selection rather than locking buyers into a fixed configuration. Measuring 38.98 x 24.21 x 10.35 in (L x W x H) and weighing 66.14 lb, the 2U4G-C621WS is sized for standard 19-inch rack cabinets in server rooms and edge data closets.

Overview

Rack-mount barebones like the 2U4G-C621WS suit environments where storage servers, virtualization hosts, or video management system (VMS) recording servers need to be built to spec rather than bought off the shelf. The 2U form factor keeps density reasonable in a shared rack without stepping up to a 4U chassis, which matters when rack unit space is shared with switches, patch panels, and other network video recorder hardware.

Key Features

• 2U Rack Form Factor: Fits standard 19-inch server racks alongside NVR and switch hardware without consuming excess vertical space — a meaningful factor in shared IT/security racks with limited rack units.
• Dual-Socket Design (model designation C621WS): Built for two Intel Xeon Scalable processors, giving integrators room to scale compute for demanding workloads like multi-stream video analytics or virtualization hosts.
• Factory-New, TW-Manufactured Build: Country of origin Taiwan, sourced as new commercial-grade hardware rather than refurbished or grey-market stock.
• 66.14 lb Chassis Weight: Confirm rack rail and cabinet load ratings before installation, particularly in multi-unit racks stacked with other heavy chassis.

Because detailed chipset, memory-channel, drive-bay, and I/O specifications were not available in verified manufacturer documentation at time of writing, this listing intentionally omits speculative configuration claims. Confirm exact CPU compatibility, RAM support, and expansion slot layout directly against AsRock's server platform documentation before finalizing a build-out, or consult a server planning guide for rack power and cooling considerations.

The 2U4G-C621WS is a dual-socket 2U barebone — the C621WS designation tells you this is built around a Xeon Scalable platform, but I want to be upfront that I don't have the full chipset and I/O spec sheet in front of me for this SKU.

Technical Highlights:

• 2U Rack Chassis: at 38.98 x 24.21 x 10.35 in, it holds standard rack depth in most cabinets — measure your rack depth against the 38.98 in length before ordering, some shallow racks won't clear it.
• 66.14 lb Bare Weight: that's before CPUs, RAM, drives, and cards go in — plan for a fully loaded weight well above that when sizing rail kits.
• Taiwan Manufacture: factory-new build, consistent with AsRock's standard production footprint for its server board lineup.

Deployment Considerations:

• This is a barebone — budget separately for CPUs, memory, storage, and any RAID or NIC add-in cards before it's rack-ready.
• I don't have confirmed drive bay count, PCIe slot layout, or power supply wattage for the 2U4G-C621WS in evidence — verify those against AsRock's published documentation before committing to a build-out.

Reasonable fit for an integrator or IT team building a custom dual-Xeon recording or virtualization server for a rack that already has 2U of space reserved — not a plug-and-play appliance.
