Custom liquid-cooled workstation

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB graphics card for high-end gaming and media production. It ships with 32GB DDR5 memory, a 4TB NVMe SSD and a 10TB hard drive in a mid-tower chassis. Windows 11 Pro is pre-installed.

Connectivity limits and storage expansion

The motherboard provides three M.2 connectors and four SATA 6Gb/s ports supporting RAID 0, 1, 5, 10 for additional drives. Wired networking reaches 2.5Gbps while wireless uses Wi-Fi 7 (802.11be) with Bluetooth 5.4. Rear I/O includes one USB4 Type-C, one USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 ports.

Compatibility checks before ordering

Verify that your workspace fits the 447 x 215 x 469 mm case dimensions and that your monitor inputs match the RTX 5090 video outputs. The 1200W 80 PLUS Gold power supply requires a suitable mains circuit. Ensure any extra memory you add is DDR5 and that replacement drives match the available M.2 or 3.5-inch bays.
