Ready-built workstation for rendering and AI

This Adamant Custom desktop arrives assembled with a 24-core Intel Core Ultra 9 285K, 128GB DDR5 memory and an Nvidia GeForce RTX 5090 32GB GPU. The 1TB Samsung 990 PRO NVMe drive and 10TB hard disk give fast boot and deep project storage. Windows 11 Pro 64-bit is pre-installed so the system is ready for heavy creative workloads immediately.

Installation notes and common pitfalls

The tower uses a Corsair 4000D chassis measuring 490 x 239 x 486 mm with a 360 mm liquid cooler already mounted. Front I/O includes one USB 3.2 Type-C and two USB 3.2 Gen 1 ports plus an audio combo jack. Rear I/O adds USB4 Type-C, USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 ports. Builders sometimes forget to connect the 2.5 Gbps Ethernet or Wi-Fi 6E antennas before first boot.

Pre-order checklist for your environment

Verify that your desk or rack can accommodate the 490 mm depth and 486 mm height of the case. Confirm the 1200 W 80 PLUS Gold power supply matches your local mains voltage and that you have a grounded outlet. The motherboard provides four M.2 slots and four SATA 6 Gb/s ports with RAID 0, 1, 5, 10 support if you plan to add drives later. Maximum memory supported is 192 GB across four DDR5 slots.
