24-Core i9-14900K Workstation

The Adamant Custom desktop pairs a 24-core Intel Core i9-14900K processor with 64GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe drive. A 360mm liquid cooler manages thermals inside an Antec P20 mid-tower case. Windows 11 Pro is pre-installed on this tower system.

Upgrade from integrated-graphics builds

This configuration replaces machines that rely on a CPU alone for display output, adding high-speed DDR5 capacity and PCIe 4.0 storage bandwidth. The jump is worth it when workloads need 24 cores and 32 threads at up to 6.00 GHz with 36 MB of L3 cache. Builders who need a discrete graphics card for rendering or gaming should look elsewhere.

64GB DDR5 and 1TB NVMe headroom

The 64GB kit fills half the board’s four slots, leaving room to reach the 192 GB maximum when memory pressure grows. Sequential reads up to 7450 MB/s and writes up to 6900 MB/s keep large project files moving. The 850W 80 PLUS Bronze PSU powers the current platform; adding a high-end GPU would require a stronger supply.

Questions about this item

What case dimensions and motherboard form factor does the Antec P20 mid-tower support for this build?

The Antec P20 mid-tower measures 469 mm deep, 220 mm wide and 490 mm high and accepts E-ATX motherboards such as the Z790 TUF Series board installed here.

How is the 360 mm AIO liquid cooler mounted, and what common step is missed during installation?

The 360 mm radiator fits in the top of the Antec P20 case with three 120 mm fans; the step often missed is removing the protective film from the cold-plate before seating it on the CPU.

Which storage slots remain free for future upgrades after the 1 TB Samsung 990 PRO is installed?

The Z790 TUF board provides four M.2 connectors; one is occupied by the 990 PRO, leaving three M.2 slots and four SATA 6 Gb/s ports available for additional drives.
