Adamant Custom
A 24-core liquid-cooled tower with 128GB DDR5, 1TB NVMe, WIFI7 and Windows 11 Pro for high-performance gaming and AI workloads
This Adamant Custom tower ships new with a 24-core Intel Core Ultra 9 285K processor, 128GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe drive. A 360mm liquid cooler keeps the CPU quiet under sustained load. Windows 11 Pro is pre-installed and the system is described as AI Ready. Integrated graphics provide USB4 and DisplayPort video outputs.
The jump makes sense when you need maximum CPU threads and unified memory for inference or compile jobs but do not require a separate GPU. Builders who need a second card for rendering or gaming should look elsewhere because the motherboard relies on integrated graphics only. The four memory slots support up to 192GB total if you plan to expand later.
Verify that your monitors accept USB4 or DisplayPort signals from the rear I/O. The 850W 80 PLUS Bronze supply powers the platform and leaves headroom for future storage in the two 3.5-inch and two 2.5-inch bays. Front-panel USB 3.2 Gen 2x2 Type-C and dual 140mm intake fans are included.

Mount the 360 mm radiator to the case, attach the pump block to the LGA 1851 socket using the supplied bracket, then connect the pump and fan cables to the motherboard headers.
Memory can be expanded to 192 GB across the four DDR5 slots; additional M.2 SSDs can use the four M.2 connectors and extra drives can fill the two 3.5-inch and two 2.5-inch bays.
