Custom Liquid-Cooled Ryzen 9 Workstation

This desktop PC ships new with a 12-core AMD Ryzen 9 9900X3D processor running at 4.4 GHz and a 240 mm liquid cooler. It includes 64 GB of DDR5 memory, a 4 TB NVMe solid-state drive, and Windows 11 Pro. The mid-tower case provides quiet operation with sound-dampening panels.

Suited For Integrated-Graphics Builds

The system relies on integrated AMD Radeon graphics with HDMI and dual USB4 video outputs, making it appropriate for productivity, development, and general multitasking. Buyers who need a discrete GPU for heavy 3D rendering or gaming at high settings should consider a different configuration.

12-Core CPU With Large Cache Decides Fit

The processor delivers 12 cores and 24 threads with 128 MB of L3 cache, reaching up to 5.50 GHz boost clocks. This specification determines whether the workstation meets compute-intensive workloads such as compilation, virtualization, or content creation.
