Adamant Custom
Liquid-cooled desktop with a 24-core Intel Core Ultra 9 285K, 64 GB DDR5, 2 TB NVMe plus 10 TB HDD and an RTX 5060 GPU
This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 64 GB of DDR5 memory and a GeForce RTX 5060 graphics card. A 360 mm liquid cooler keeps the CPU stable under sustained loads. The system ships with Windows 11 Pro installed and is marketed as AI ready for local inference workloads. It targets creators and engineers who need high thread counts and fast storage in a single chassis.
The mid-tower Ceres 300 enclosure uses tempered glass panels and includes front-panel USB 3.2 Gen 2 Type-C, two USB 3.0 ports and HD audio jacks. Two 140 mm front fans and one 140 mm rear fan run at 1500 rpm with a rated 30 dBA noise level. Internal bays support one 3.5-inch or two 2.5-inch drives, while the motherboard adds four SATA and four M.2 connectors. A Thermaltake Smart 850 W 80 PLUS Bronze unit with Japanese main capacitors supplies power.
Primary storage is a 2 TB Samsung 990 PRO PCIe 4.0 x4 NVMe drive rated for up to 7450 MB/s read and 6900 MB/s write. A 10 TB hard drive with 256 MB cache provides bulk capacity for media libraries and archives. The Z890 motherboard offers four M.2 slots total, leaving room for future SSD expansion. Buyers who need more than two high-speed NVMe volumes should verify slot allocation before ordering.

The Ceres 300 mid-tower measures 475 mm deep by 245 mm wide by 463 mm high and fits ATX boards such as the Z890 TUF motherboard.
The 360 mm radiator mounts to the front of the case with three 140 mm fans; the step often missed is removing the protective film from the cold-plate before seating it on the CPU.
