AsRock EC266D4U Micro-ATX Single Socket Server Motherboard

Overview

The AsRock EC266D4U is a micro-ATX, single-socket server motherboard built for compact rack and tower server chassis where board footprint is a hard constraint. Referenced under the extended part designation EC262D4U2-2L2Q/E810, this board targets integrators who need a small-form-factor server platform without stepping down to embedded or SoC-class hardware. At 9.60 x 9.60 x 4.00 in and 2.65 lb, it fits standard micro-ATX chassis cutouts and drive-bay-constrained 1U/2U enclosures common in edge server and NVR host builds.

Key Features

• Micro-ATX form factor (9.60 x 9.60 in): matches standard micro-ATX chassis mounting points, so it drops into existing rack and tower enclosures without a custom tray.
• Single-socket design: keeps the platform footprint and power draw predictable for single-CPU server and appliance builds rather than dual-socket density.
• Compact 4.00 in depth: relevant for short-depth rack chassis and edge-deployment enclosures where a full-depth board won't clear the front bezel or cable routing.
• Light board weight (2.65 lb): keeps shipped chassis assemblies under typical carrier weight brackets when building out multiple units for a rollout.
• Factory-new, CN country of origin: sourced as new production, not refurbished or pulled from decommissioned systems.

Integration & Compatibility

The EC266D4U is sized for micro-ATX server and NVR-host chassis already standard in commercial-grade rack deployments. Confirm CPU socket type, chipset, RAM class, and expansion slot layout directly against the board's printed model markings before ordering replacement chassis or a matching CPU/RAM kit, since those details are not confirmed in the specifications on hand for this listing. If you're speccing a full recording or VMS server around this board, review a network video recorders buildout or an architecture guide for storage and channel-count planning before finalizing the platform.

Marty Allison

The AsRock EC266D4U is a straightforward pick when the deciding constraint is physical: 9.60 x 9.60 in micro-ATX footprint, 4.00 in depth, single-socket layout. I get asked about board fitment more than raw spec sheets on short-depth builds, and this is one where the dimensions do the talking.

Technical Highlights:

• Micro-ATX, 9.60 x 9.60 in: standard mounting pattern — no custom tray needed in most rack or tower chassis rated for micro-ATX.
• 4.00 in board depth: a real factor in short-depth 1U/2U enclosures where full-depth ATX or E-ATX boards won't clear the front panel.
• 2.65 lb board weight: keeps a multi-unit chassis rollout under typical per-unit shipping weight thresholds.

Deployment Considerations:

• Verify CPU socket, chipset, and RAM generation against the board's own silkscreen or the full AsRock spec sheet before ordering a matching CPU and memory kit — those weren't confirmed in the data available for this listing.
• Single-socket design means this isn't the board for dual-CPU density builds; if you need that, look elsewhere in AsRock's rack/server board lineup.

Good fit for a compact edge-server or NVR-host build where micro-ATX footprint and short board depth are the binding constraints on chassis selection. Confirm CPU/RAM compatibility against the EC266D4U's full spec sheet before finalizing a build-out.
