Adamant Custom 12-Core Liquid-Cooled Workstation

The Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and a 2TB Samsung 990 PRO NVMe drive. A 240mm liquid cooler keeps the CPU stable under sustained workloads while the system runs Windows 11 Pro out of the box.

Suited to creators needing high memory capacity

Editors and developers who rely on large project files benefit from the 128GB DDR5 configuration and 7450 MB/s sequential reads. Buyers who need more than four M.2 slots or a second graphics card should look at a different platform.

128GB DDR5 across four slots defines upgrade scope

The motherboard populates all four DIMM slots to reach 128GB, leaving no free sockets for expansion. Maximum supported capacity is 192GB, so any future increase requires replacing existing modules rather than adding to them.

Questions about this item

What are the case dimensions and internal drive bay sizes for this desktop?

The Corsair 4000D case measures 490 x 239 x 486 mm and includes two 3.5-inch and two 2.5-inch internal bays.

How is the 240mm liquid cooler installed, and what step is often missed?

Mount the radiator to the case fan positions, then attach the pump block to the AM5 socket using the supplied backplate; the step often missed is orienting the pump so its tubing does not strain the CPU block.

When will the 850W Bronze PSU or the 240mm AIO liquid cooler need replacement?

The Thermaltake 850W PSU typically lasts 7–10 years; the 240mm AIO coolant should be refreshed or the unit replaced after about 5 years to maintain pump performance.
