A liquid-cooled desktop with an 8-core Ryzen 7 9700X, 32GB DDR5, 2TB NVMe SSD and integrated Radeon graphics runs Windows 11 Pro
This Adamant Custom desktop arrives as a complete gaming workstation built around an 8-core AMD Ryzen 7 9700X processor. It ships with 32GB of DDR5 memory and a 2TB Samsung 990 PRO NVMe drive inside a Corsair 4000D tempered-glass chassis. Windows 11 Pro is pre-installed and the system is described as AI ready for modern workloads.
The integrated Radeon graphics handle display output through HDMI and two USB4 ports, so the machine works immediately without a discrete card. Builders who want higher frame rates in modern titles can add a dedicated GPU later using the available PCIe slot and the 750W power supply. The four memory slots support up to 192GB total for future expansion.
The system arrives fully assembled with a 240mm liquid cooler already mounted, so no cooler installation is required. Adding a graphics card means removing the side panel and securing the card to the case bracket, then connecting power cables from the Thermaltake unit. The motherboard includes four M.2 connectors for additional NVMe drives if more storage is needed.

The chassis measures 490 mm deep, 239 mm wide and 486 mm high. Allow extra space at the rear for cable routing and the liquid cooler tubing.
The radiator and two 140 mm fans are pre-fitted to the top of the case. The step people forget is removing the protective film from the CPU cold-plate before locking the pump block onto the AM5 socket.
You can add up to 192 GB of DDR5 across the four slots, install three more M.2 NVMe drives, and populate the two 3.5-inch and two 2.5-inch drive bays. The AM5 socket also supports future Ryzen CPUs.
