Ready-to-run workstation

This desktop ships with Windows 11 Pro installed and a liquid-cooled Ryzen 9 9900X3D at its core. The 12-core processor reaches 5.50 GHz boost and includes 128 MB of L3 cache for heavy multi-threaded loads. Creative professionals and engineers can start rendering or compiling immediately.

Standard ATX assembly

The CoolerMaster HAF 500 mid-tower uses regular ATX mounting points and a 240 mm AIO that fits the supplied X870-PLUS TUF motherboard. Four DDR5 slots are populated with 128 GB, leaving no free DIMM sockets for later expansion. Builders should verify case clearance for the 200 mm front fans before adding extra drives.

PCIe 4.0 storage ceiling

The 4 TB Samsung 990 PRO operates at PCIe 4.0 x4 with sequential reads up to 7450 MB/s and writes up to 6900 MB/s. That bandwidth caps large-file throughput regardless of the GPU or CPU headroom. Users needing sustained writes beyond this limit must add drives rather than rely on the single boot volume.

Questions about this item

How do I confirm the Ryzen 9 9900X3D is hitting its 5.50 GHz boost and the 240 mm liquid cooler is keeping thermals in check?

Open Task Manager or HWMonitor after a heavy load; the CPU should show speeds up to 5.50 GHz with the 128 MB L3 cache active, while coolant temperature stays steady thanks to the 240 mm AIO Quiet Edition cooler.

What components come pre-installed in the CoolerMaster HAF 500 case and what must I add myself?

The build ships with the X870-PLUS TUF motherboard, 128 GB DDR5, 4 TB Samsung 990 PRO SSD, RTX 5070 12 GB GPU, 850 W 80 PLUS Bronze PSU, Windows 11 Pro, front 200 mm ARGB fans, rear 120 mm ARGB fan and GPU fan; no extra parts are required unless you want more storage in the two 3.5" or two 2.5" bays.

Should I choose the 128 GB DDR5 configuration or upgrade toward the 192 GB maximum the board supports?

The 128 GB kit fills all four slots with high-performance DDR5 and suits most workstation and gaming workloads; only move to 192 GB if you run memory-heavy simulations or virtualization that regularly exceed the current capacity.
