Adamant Custom
A liquid-cooled gaming desktop with a 20-core Intel Core Ultra 7 265K, 32 GB DDR5, 4 TB NVMe storage and an RTX 5080 GPU
The Adamant Custom desktop pairs a 20-core Intel Core Ultra 7 265K processor with a 240mm liquid cooler and an Nvidia GeForce RTX 5080 graphics card. Thirty-two gigabytes of DDR5 memory and a 4TB Samsung 990 PRO NVMe SSD provide fast throughput for modern games and content-creation workloads. Windows 11 Pro comes pre-installed on a system built for high-frame-rate play and media editing.
Builders moving from platforms limited to air cooling or fewer cores gain headroom for sustained multi-threaded rendering and 4K gaming. The Z890 motherboard supports up to 192 GB of DDR5 across four slots, so memory can scale with future project demands. The 1000W 80 PLUS Gold power supply delivers stable current for the installed GPU and additional storage drives.
The 4TB NVMe drive operates at PCIe 4.0 speeds, capping sequential reads at 7450 MB/s and writes at 6900 MB/s; faster PCIe 5.0 drives would not exceed this interface ceiling. Rear I/O includes Thunderbolt 4, USB 20Gbps and 10Gbps ports, while Wi-Fi 7 and 2.5Gb Ethernet set the network throughput ceiling. Four M.2 slots and four SATA ports define the maximum internal drive count.

The Antec P20 mid-tower measures 469 mm deep, 220 mm wide and 490 mm high and accepts E-ATX motherboards such as the Z890 TUF board installed here.
The AIO radiator attaches to the case fan mounts with the supplied brackets; the step people forget is connecting the pump header and the RGB or fan cables to the motherboard before closing the panel.
The 140 mm PSU fan and the three 120 mm front case fans are the only moving parts besides the pump, so they will require cleaning or replacement before any solid-state component.
