AsRock 1U4LW-X570/2L2T 1U Rackmount Server Barebone

Overview

The AsRock 1U4LW-X570/2L2T is a 1U rackmount server barebone built around the AM4 socket for AMD Ryzen PGA1331 processors, targeting integrators who need dense rack compute without committing to a pre-configured system. As a barebone, it ships as the chassis, motherboard platform, and I/O foundation — you select and install the CPU, memory, and drives to match the workload, whether that's a video management server, edge recording node, or general-purpose rack server in a security operations center. At 31.80 x 25.20 x 9.06 inches and 38.27 lb, it occupies a single rack unit while still accommodating a 4-bay hot-swap drive configuration (4LW in the model name signals the four-bay layout). The 1U4LW-X570/2L2T (often searched as 1U4LW X570/2L2T) is manufactured in Taiwan, giving buyers a documented country of origin for procurement and compliance paperwork.

Key Features

• AM4 Socket / PGA1331 support: Accepts AMD Ryzen desktop-class CPUs in a server chassis, which means access to Ryzen's strong single-thread performance for workloads like VMS servers or analytics engines that don't need dual-socket Xeon horsepower — lower platform cost per rack unit for small-to-midsize deployments.
• 1U rack form factor: A single rack unit footprint (31.80 x 25.20 x 9.06 in) means you can stack four of these in a 4U section of a rack alongside switches and NVR appliances without burning excess vertical space in a crowded server closet.
• 4-bay hot-swap drive layout (4LW): Four accessible drive bays let you build out RAID storage for recording retention or database workloads and swap a failed drive without powering down the chassis — relevant for any deployment where downtime during a drive replacement isn't acceptable.
• Dual 2L2T LAN (dual 2.5GbE): The 2L2T designation points to dual 2.5 Gigabit Ethernet ports on board, giving you a dedicated management/failover path or link aggregation for higher-throughput ingest — useful when this barebone is feeding video streams from a camera network into local storage.
• Barebone flexibility: Because the CPU, RAM, and drives aren't locked in at the factory, you can size the build to the job — a lighter Ryzen 5 for a modest recording load, or a higher core-count Ryzen chip if the box is also running analytics or virtualization.
• 38.27 lb chassis weight: Heavier gauge steel construction than a typical desktop case, which matters when the unit is going into a rack that will see repeated drive service and cable routing over its service life.

Integration & Compatibility

As a barebone platform, the 1U4LW-X570/2L2T integrates into standard 19-inch rack cabinets alongside network video recorders and PoE network switches in a security infrastructure rack. Because it's a bare chassis rather than a locked-down appliance, it pairs well with a broader AsRock hardware catalog for buyers standardizing on one motherboard vendor across a deployment. If you're scoping out how a server like this fits into a larger camera and storage build, a VMS architecture guide is worth reviewing before finalizing CPU and drive selection — the right balance between the 4-bay storage layout here and your expected retention window depends on camera count and resolution. For rack-scale deployments, plan power and network drops using a PoE planning guide alongside this unit's dual 2.5GbE uplinks, and browse rackmount servers if you need a comparison point against fully configured systems.

What's in the Box

Ships as a barebone unit: 1U4LW-X570/2L2T chassis with AM4/PGA1331 motherboard platform pre-installed and 4-bay hot-swap drive cage. CPU, memory, and storage drives are sourced separately to match your build.

Frequently Asked Questions

Q: What CPUs does the 1U4LW-X570/2L2T support?

A: It uses an AM4 (PGA1331) socket, which accepts AMD Ryzen desktop-class processors compatible with the AM4 platform. This is a barebone — the CPU is not included and must be sourced to match your workload.

Q: How many drives can the 1U4LW-X570/2L2T hold?

A: The chassis includes a 4-bay hot-swap drive layout, indicated by the '4LW' designation in the model name.

Q: What networking does the 1U4LW-X570/2L2T include?

A: Dual 2.5GbE LAN ports, indicated by the '2L2T' designation in the model name.

Q: What are the dimensions and weight of the 1U4LW-X570/2L2T?

A: The chassis measures 31.80 x 25.20 x 9.06 inches and weighs 38.27 lb, occupying a single rack unit (1U).

Q: Where is the 1U4LW-X570/2L2T manufactured?

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

Q: Does the 1U4LW-X570/2L2T include RAM and storage?

A: No — it ships as a barebone chassis and motherboard platform. Memory and drives are purchased separately to match your intended workload.

Marty Allison

The 1U4LW-X570/2L2T lands on my bench whenever a client wants Ryzen performance in a 1U rack slot instead of a locked-down OEM appliance. The AM4/PGA1331 socket is the headline here — it opens the door to Ryzen desktop silicon in a rack form factor, which isn't something every 1U barebone offers.

Technical Highlights:

• 4-bay hot-swap (4LW): Four drive bays accessible without powering down the chassis, so a failed disk in a live recording or database server doesn't mean a maintenance window.
• Dual 2.5GbE (2L2T): Two 2.5 Gigabit Ethernet ports on board give you room to split management traffic from ingest traffic, or bond them for higher aggregate throughput.
• 1U footprint at 38.27 lb: Measuring 31.80 x 25.20 x 9.06 in, it packs a 4-bay array into a single rack unit — dense, but plan your rail and cable management accordingly given the depth.

Deployment Considerations:

• This is a barebone: budget separately for the Ryzen CPU, memory, and the drives that populate the 4-bay cage before it's rack-ready.
• AM4 is a desktop-class socket, not a dual-socket server platform — right-sized for single-CPU workloads, not a fit if you need multi-socket scaling.

I spec the 1U4LW-X570/2L2T for edge VMS deployments where a customer wants dedicated on-prem recording and storage in a shared rack with networking gear, and doesn't need more than one CPU socket's worth of horsepower to get there.
