Custom liquid-cooled workstation

This Adamant Custom tower ships new with a 24-core Intel Core Ultra 9 285K processor, 32GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card with 32GB of video memory. A 360mm AIO cooler handles CPU thermals while the Gigabyte Z890 Eagle motherboard provides Wi-Fi 7 and 2.5Gbps Ethernet. Windows 11 Pro is pre-installed on an 8TB NVMe array built from two Samsung 990 PRO drives.

Creators who need GPU memory and expandable RAM

The four DIMM slots support up to 192GB of DDR5, so studios running large textures or virtual machines can add capacity later. Buyers who want more storage bays than the two 3.5-inch and two 2.5-inch internal mounts provide should look at a different chassis. The single graphics card configuration also means this system does not suit multi-GPU compute clusters.

32GB RTX 5090 frame buffer

The decisive specification is the graphics card’s 32GB of onboard memory, which lets the system hold entire 8K timelines or massive AI models without paging to system RAM. If your workload fits in less video memory, a smaller GPU will cost less and draw less power.

Questions about this item

How much clearance does the 360 mm liquid cooler need in the 447 x 215 x 469 mm tower?

The 360 mm radiator mounts in the case roof or front; the 469 mm height and 447 mm depth give enough room for the radiator plus two 140 mm fans without fouling the motherboard or GPU.

Which CPU power connectors must be seated on the Z890 EAGLE board for the 24-core Ultra 9 285K?

Plug both the 24-pin ATX and the 8+4-pin EPS cables from the 1200 W PSU; the 8-pin alone will not deliver enough current for 5.70 GHz boost clocks.

When should the AIO coolant be checked or the loop refreshed?

Inspect tubing and fittings for seepage every 12 months; plan a full coolant flush and refill at the 3-to-5-year mark to keep the 24-core CPU at safe temperatures.
