20-Core AI Workstation

This business desktop combines a 20-core Intel Core Ultra 7 265K processor with 64GB DDR5 memory and an Nvidia RTX PRO 2000 Blackwell 16GB GPU. It targets engineers and designers running SolidWorks CAD modelling and local AI inference workloads. The system ships with Windows 11 Pro and a 240mm liquid cooler for sustained performance.

Upgrade From Older Workstations

The jump is worth it when your current machine chokes on large assemblies or lacks GPU memory for AI-assisted design. Twenty cores at up to 5.50 GHz with 30 MB L3 cache cut simulation times, while 16GB VRAM fits larger models. Buyers who need more than 192GB total memory or multiple GPUs should look elsewhere.

Straightforward Rack Integration

The Antec P10 FLUX mid-tower arrives fully assembled with the 850W PSU and liquid loop pre-installed. Connect power, network and peripherals to the rear I/O — including 2.5G Ethernet, Wi-Fi 7 and Thunderbolt 4 — then boot. The only common snag is forgetting to seat the GPU power cables after transit vibration.

Questions about this item

What case clearance is needed for the 240 mm liquid cooler?

The Antec P10 FLUX mid-tower measures 477 x 220 x 486 mm and mounts the 240 mm AIO at the front or top with standard 120 mm fan spacing.

Which motherboard headers connect the 240 mm AIO pump and fans?

Plug the pump into the CPU_OPT or AIO_PUMP header and the two 120 mm fans into CPU_FAN and CPU_FAN2 on the Z890-PLUS TUF board.

When should the 10 TB hard drive be checked or replaced?

Monitor SMART attributes annually; plan replacement once reallocated-sector count rises or after the rated workload limit is reached.
