Liquid-cooled tower with a 12-core Ryzen 9 9900X3D, 192GB DDR5, 1TB NVMe SSD and 10TB HDD
This desktop arrives ready to run Windows 11 Pro on a 12-core Ryzen 9 9900X3D processor cooled by a 240 mm liquid loop. The tower case holds 192 GB of DDR5 memory, a 1 TB NVMe boot drive and a 10 TB hard drive for bulk storage. Integrated Radeon graphics drive the display outputs while the system targets AI-ready workloads and high-refresh gaming alike.
The only GPU present is the processor's integrated Radeon engine, so 3D performance tops out at light esports titles and desktop acceleration. Demanding AAA games, GPU compute workloads or multi-monitor 4K gaming will require a discrete card that this chassis can accommodate. Buyers who need more graphics power must plan to add one themselves.
The 1 TB NVMe drive provides fast OS and application space, while the 10 TB mechanical drive absorbs large media libraries and project archives. Memory is maxed at the platform limit of 192 GB across four slots, leaving no room for further RAM upgrades without replacing modules.

The processor can reach 5.50 GHz on active cores, giving snappy single-thread performance for gaming and light productivity while the 128 MB L3 cache keeps multi-threaded tasks responsive across 12 cores and 24 threads.
Each USB4 port runs at 40 Gbps, so large file transfers to compatible external SSDs or docks are limited only by the drive speed, not the port.
The system ships in a tower measuring 447 x 215 x 469 mm with a 240 mm AIO and TUF X870-PLUS ATX board, so it occupies a typical mid-tower footprint.
