Workstation desktop with 20-core CPU

The Adamant Custom system centres on an Intel Core Ultra 7 265K processor with 20 cores running at 3.9 GHz. It ships with 192 GB of DDR5 memory and a 4 TB NVMe solid-state drive plus a 10 TB hard drive. Windows 11 Pro 64-bit is pre-installed and the machine is described as AI Ready for local inference workloads.

Liquid-cooled chassis with front and rear I/O

A 240 mm liquid cooler keeps the CPU quiet under sustained load. The Corsair 4000D tempered-glass case provides internal bays for two 3.5-inch and two 2.5-inch drives. Front panel includes one USB 3.2 Type-C port, two USB 3.2 Gen1 ports and a combo audio jack; rear I/O adds Thunderbolt 4, USB 20 Gbps and 10 Gbps ports, 2.5G Ethernet, Wi-Fi 7 and Bluetooth 5.4.

Replaces older multi-threaded workstations

The 20-core configuration upgrades from earlier desktops limited to fewer threads for CAD modelling and simulation. The RTX PRO 2000 Blackwell GPU with 16 GB VRAM supports professional visualisation and VR workflows. Buyers who need more than 192 GB of memory or multiple high-end GPUs should consider a different platform.

Questions about this item

Does the Thunderbolt 4 port on the Z890 motherboard run at the full 40 Gbps or is it limited by the chipset?

The rear Thunderbolt 4 Type-C port is wired to the Intel Z890 chipset and operates at the full Thunderbolt 4 specification of 40 Gbps.

What drive bays and M.2 slots are free inside the Corsair 4000D case for adding more storage?

The case provides two internal 3.5-inch bays and two 2.5-inch bays; the motherboard has four M.2 connectors, one occupied by the 4 TB Samsung 990 PRO, leaving three open for additional NVMe SSDs.

What is the correct order to seat the 192 GB DDR5 kit and the 240 mm AIO cooler on the LGA 1851 socket?

Install the CPU into the LGA 1851 socket first, then mount the AIO water block before populating all DDR5 slots; reversing the order blocks access to the memory latches.
