Built for heavy compute

This desktop ships with a 24-core Intel Core Ultra 9 285K, 192 GB DDR5, an RTX 5090 32 GB GPU, 8 TB NVMe storage and a 10 TB hard drive. It targets professionals running large rendering, modelling or AI learning workloads that need both high thread counts and massive GPU memory in a single tower.

Replacing a workstation split across two machines

The jump makes sense when a single project no longer fits in 64 GB RAM or when a 24 GB GPU forces texture streaming that slows iteration. Consolidating CPU threads, GPU VRAM and fast local storage into one liquid-cooled chassis removes network latency between nodes and simplifies licence management.

Straightforward assembly with one cabling catch

The Corsair 4000D case, 1200 W Gold PSU and pre-filled 360 mm AIO arrive fully built; Windows 11 Pro is installed and validated. The only common issue is routing the stiff 12 V HPWR cable to the RTX 5090 without bending the connector beyond its rated radius, which can cause intermittent power delivery.

Questions about this item

How deep is the Corsair 4000D case so I can check desk clearance?

The chassis measures 490 mm deep, 239 mm wide and 486 mm high; allow extra space at the rear for cable routing and the 360 mm radiator exhaust.

What is the main installation step people miss when fitting the 360 mm AIO cooler?

Mount the radiator with tubes at the bottom or side, not the top, then fill the loop by running the pump at full speed for several minutes until bubbles clear.

Which drives will need replacement first under heavy write workloads?

The two 4 TB Samsung 990 PRO SSDs handle the OS and scratch files; their endurance rating is lower than the 10 TB HDD, so plan to swap them sooner.
