AsRock 4U18N-AM5/2T 4U 18-Bay AM5 Server Barebone

Overview

The AsRock 4U18N-AM5/2T is a 4U rack-mount server barebone built around the AM5 (LGA 1718) socket platform, supporting AMD EPYC 4005/4004 series processors. Model 4U18N-AM5/2T (often searched as 4U18N AM5/2T) targets integrators assembling storage-dense or compute-dense rack builds where chassis, socket platform, and drive bay layout need to be selected before the rest of the build is finalized.

Key Features

AM5 (LGA 1718) socket platform: supports AMD EPYC 4005/4004 series processors, giving you a current AMD server core to build around rather than a legacy socket you'll need to plan an early refresh cycle for.

4U rack form factor: the 4U height accommodates higher-capacity cooling and drive bay density than a 1U or 2U chassis, which matters when you're planning airflow and serviceability in a shared rack.

18-bay chassis designation: the "18N" naming indicates an 18-bay drive layout — relevant for storage-dense deployments where bay count drives your usable capacity planning before you've picked a single drive.

245.07 lb shipping weight: plan freight, loading dock access, and rack rail weight ratings accordingly — this is a heavier chassis than typical 1U/2U compute nodes and should factor into your rack and lift planning.

Taiwan (TW) country of origin: manufactured in Taiwan, relevant for organizations tracking country-of-origin documentation for procurement or compliance review.

Integration & Compatibility

The 4U18N-AM5/2T pairs with AMD's AM5 (LGA 1718) socket ecosystem, positioning it for EPYC 4005/4004 series builds. Confirm memory, drive, and expansion card compatibility against your specific processor and workload before finalizing a build-out — full I/O, memory channel, and expansion slot detail was not available at the time of writing.

Frequently Asked Questions

Q: What processors does the 4U18N-AM5/2T support?

A: It uses the AM5 (LGA 1718) socket and supports AMD EPYC 4005/4004 series processors.

Q: How many drive bays does the 4U18N-AM5/2T have?

A: The "18N" designation indicates an 18-bay chassis layout.

Q: How much does the 4U18N-AM5/2T weigh for freight planning?

A: The barebone chassis weighs 245.07 lb — factor this into loading dock and rack lift planning.

Q: Where is the 4U18N-AM5/2T manufactured?

A: Taiwan (TW) is listed as the country of origin.

The 4U18N-AM5/2T is one of the heavier barebones I've spec'd out recently — 245.07 lb before you've added a single drive, CPU, or PSU. That number alone tells you this is an 18-bay chassis built for density, not a lightweight edge box.

Technical Highlights:

AM5 (LGA 1718) socket: current-generation AMD platform supporting EPYC 4005/4004 series chips — gives you a modern socket to plan around instead of committing to hardware near end-of-life.
4U chassis height: more airflow and drive bay room than 1U/2U alternatives, which matters once you're running 18 bays' worth of drives under load.
245.07 lb bare chassis weight: get your rack rails and floor loading confirmed before this shows up on the dock — this isn't a two-person lift.

Deployment Considerations:

Full memory channel count, expansion slots, and PSU wattage weren't in the documentation available here — get those confirmed against your exact EPYC 4005/4004 SKU before finalizing a bill of materials.
At 245.07 lb unpopulated, budget for freight handling and rack installation labor, not just the shipping cost line.

Reach for the 4U18N-AM5/2T when you're building an AM5-platform storage or compute node that needs 18-bay density in a 4U footprint — not for edge or space-constrained deployments where a 1U or 2U chassis fits better.
