Adamant Custom 12-Core Liquid Cooled Gaming PC

This new desktop system ships with Windows 11 Pro and a 12-core AMD Ryzen 9 9900X3D processor. It includes 64GB DDR5 memory, a 1TB NVMe SSD and integrated AMD Radeon graphics. Liquid cooling and an 850W power supply complete the build.

Who This Suits and Who Should Look Elsewhere

The PC suits users who need high multi-thread performance and fast storage in a ready-to-use tower. Buyers who want a discrete graphics card for heavy 3D rendering or competitive gaming should look at a different configuration.

Integrated AMD Radeon Graphics

The system relies on integrated AMD Radeon graphics with HDMI and two USB4 outputs. No discrete GPU is installed, so graphical workloads run on the processor's built-in engine. This decides whether the machine fits your workload.

Questions about this item

What case dimensions and drive bays does the Corsair 4000D provide for this build?

The case measures 490 x 239 x 486 mm and includes two 3.5-inch and two 2.5-inch internal bays.

How is the 240 mm liquid cooler mounted, and what step is often missed?

The AIO radiator attaches to the case fan mounts; the step many miss is removing the protective film from the cold-plate before seating it on the CPU.

Which components can be upgraded later and what are the limits?

Memory can be expanded to 192 GB across four DDR5 slots, and additional M.2 or SATA drives can be added using the motherboard's four M.2 connectors and two SATA ports.
