Ready-to-run workstation for modelling and AI

This desktop ships with Windows 11 Pro installed and a 12-core Ryzen 9 9900X3D processor cooled by a 240 mm liquid loop. The 192 GB DDR5 memory and 1 TB NVMe SSD are already configured, so the system is ready for modelling, video editing, rendering and AI learning workloads without further assembly.

Suits creators who need maximum memory and GPU power

The 32 GB RTX 5090 graphics card and 192 GB DDR5 capacity serve professionals running large datasets or complex scenes. Buyers who need more than 1 TB of fast storage or who require multiple additional drive bays should look at a different configuration.

192 GB DDR5 is the deciding specification

Four slots are populated to reach the motherboard's 192 GB limit, leaving no room for future memory upgrades. If your workflow demands more than 192 GB of system memory, this platform cannot accommodate it.
