Adamant Custom
Liquid-cooled mid-tower desktop with 24-core Intel Core Ultra 9 285K, 192GB DDR5, 4TB NVMe SSD and RTX 5070 graphics for high-end gaming and media work
The Adamant Custom system ships as a new mid-tower workstation built around a 24-core Intel Core Ultra 9 285K processor and a 360 mm liquid cooler. It runs Windows 11 Pro on 192 GB of DDR5 memory and a 4 TB NVMe SSD. An Nvidia GeForce RTX 5070 graphics card with 12 GB of video memory handles gaming and creative workloads. The 850 W 80 PLUS Bronze power supply provides stable delivery for all components.
This configuration fits professionals who need many CPU threads, large memory capacity and a modern GPU in a single chassis. It is not for buyers who want more storage bays than the two 3.5-inch and two 2.5-inch internal slots provide. It is not for builders who need a second graphics card because the motherboard layout and power budget target a single GPU. It is not for users who require an optical drive or a different operating system out of the box.
The motherboard supports a maximum of 192 GB and all four slots are already populated with high-performance DDR5 modules. Any future memory upgrade would require replacing the existing kit rather than adding sticks. This capacity ceiling is the single specification that decides whether the system can grow with your workload or must be replaced when demands increase.

The Samsung 990 PRO SSD connects via PCIe 4.0x4 and delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s.
The Corsair 4000D measures 490 mm deep, 239 mm wide and 486 mm high and accommodates standard ATX motherboards such as the included GIGABYTE Z890 UD.
The 360 mm AIO radiator mounts to the case with supplied brackets and fans; the step often missed is removing the protective film from the cold-plate before seating it on the LGA 1851 socket.
