20-Core Liquid-Cooled Workstation

The Adamant Custom desktop pairs a 20-core Intel Core Ultra 7 265K processor with 128GB of DDR5 memory and a 240mm liquid cooler. A GeForce RTX 5070 graphics card with 12GB of video memory drives the visual output. The system ships with Windows 11 Pro installed and is aimed at professionals who need high multi-threaded throughput alongside modern GPU acceleration.

Upgrade From Older Thread-Limited Rigs

Builders moving from platforms capped at lower core counts or slower memory will see the largest gains in compile times, render queues and multi-tasking headroom. The jump is most worthwhile when current workloads saturate available threads or exceed 64GB of system memory. The 4TB NVMe boot drive and 10TB mechanical store provide ample capacity for active projects and archives without external arrays.

Straightforward Integration With Standard Parts

The Antec P20 mid-tower uses common ATX mounting points and a 750W 80 PLUS Bronze supply with standard cable routing. Front-panel USB 3.2 Gen 2 Type-C and Thunderbolt 4 ports connect directly to the Z890 motherboard headers. Installers should verify cooler clearance against the 469mm case depth and ensure the 140mm PSU fan orientation matches the bottom vent.
