Built for modelling and AI workstations

This desktop pairs a 12-core Ryzen 9 9900X3D processor with an RTX 5090 graphics card and 64GB of DDR5 memory. A 1TB NVMe SSD provides fast storage for large datasets. The system ships with Windows 11 Pro and a 240mm liquid cooler for sustained workloads.

Upgrading from air-cooled or lower-core systems

Moving from a machine with fewer cores or a smaller GPU reduces render and training times for 3D modelling, video editing and AI learning tasks. The jump is worth it when projects exceed the memory or compute limits of your current hardware.

Suits creators and researchers needing local GPU

Buyers who rely on cloud instances for heavy inference or rendering gain a dedicated 32GB GPU and high-speed local storage. Teams requiring multiple GPU slots or more than 192GB of system memory should evaluate alternative configurations.

Questions about this item

Will the Corsair 4000D case dimensions of 490 x 239 x 486 mm fit my desk space?

The case measures 490 mm deep, 239 mm wide and 486 mm high. Allow a few centimetres extra at the rear for cable routing and the 140 mm PSU fan exhaust.

What is the correct orientation for the 240 mm AIO radiator and which header powers the pump?

Mount the radiator with tubes at the bottom or side to avoid air bubbles, then connect the pump cable to the motherboard AIO_PUMP or CPU_FAN header so speed is reported in BIOS.

When should I plan to replace the AIO liquid cooler or its fans?

A sealed 240 mm AIO typically runs 4 to 6 years before pump wear or coolant loss appears; the 140 mm radiator fans can be swapped earlier if noise rises.
