System Configuration

The Adamant Custom gaming desktop combines a 12-core AMD Ryzen 9 9900X3D processor with 128GB DDR5 memory and an AMD Radeon RX 9070 XT graphics card. A 240mm liquid cooler manages CPU thermals inside an Antec P20 mid-tower case. Windows 11 Pro comes pre-installed on the 8TB NVMe storage array.

Target Audience

This workstation suits creators and engineers who need high core counts, large memory capacity and fast local storage for rendering, simulation or compilation workloads. Buyers who want more storage bays than the two 3.5-inch and two 2.5-inch internal slots should look at larger chassis options. Systems without liquid cooling or with lower memory ceilings will not match this configuration.

Deciding Specification

The 128GB DDR5 memory kit occupies all four motherboard slots and reaches the platform limit of 192GB maximum supported capacity. Users who anticipate needing more than 192GB total memory must choose a different platform before purchase.
