24-Core Workstation Desktop

The Adamant Custom mid-tower desktop ships new with Windows 11 Pro and a 24-core Intel Core i9-14900K processor. Liquid cooling keeps the CPU stable under sustained multi-threaded loads. It targets professionals who need high core counts and large memory capacity in a single workstation.

128GB DDR5 Memory Capacity

Four slots hold 128GB of DDR5 with a 192GB ceiling for future expansion. The platform uses DDR5 exclusively; no other memory generation fits. Buyers who need more than 192GB total system memory cannot upgrade beyond the motherboard limit.

4TB NVMe Storage Headroom

A Samsung 990 PRO 4TB drive delivers up to 7450 MB/s reads and 6900 MB/s writes over PCIe 4.0x4. Four M.2 connectors remain on the Z790 board for additional NVMe drives. Builders who require mechanical hard drives or optical media will find no bays or controllers for them.

Questions about this item

What does the 6.00 GHz boost clock mean once the i9-14900K is inside this liquid-cooled build?

The 24-core i9-14900K can reach 6.00 GHz on its performance cores when thermals allow, and the 360 mm liquid cooler keeps temperatures low enough to sustain that speed during heavy workloads.

How does the PCIe 4.0 x4 link cap the Samsung 990 PRO 4 TB SSD in practice?

The drive connects through a PCIe 4.0 x4 M.2 slot, so sequential reads top out near 7450 MB/s and writes near 6900 MB/s — the interface ceiling for this generation.

What clearance does the 360 mm AIO need to fit in the Antec P20 case?

The 360 mm radiator mounts in the front of the 469 mm deep mid-tower, using the three included 120 mm front fans as intake for the liquid cooler.
