A liquid-cooled tower with a 16-core Ryzen 9 9950X, 128GB DDR5, RTX 5070, 1TB NVMe and 10TB HDD for gaming and media work
This Adamant Custom tower pairs a 16-core AMD Ryzen 9 9950X with 128GB of DDR5 memory and a GeForce RTX 5070 graphics card. The system targets content creators and engineers who need high thread counts for rendering, simulation or heavy multitasking. A 1TB NVMe boot drive and 10TB hard drive provide fast primary storage and deep archival capacity. Windows 11 Pro is pre-installed.
The chassis measures 447mm deep, 215mm wide and 469mm high and includes a 360mm liquid cooler that needs matching radiator clearance. An 850W 80 PLUS Bronze power supply is fitted; confirm your mains voltage and outlet type suit this unit. The motherboard offers four memory slots, all populated, so future upgrades require module replacement. Rear I/O includes USB4 Type-C, USB 3.2 Gen 2, USB 3.2 Gen 1 and four USB 2.0 ports.
Buyers who rely on many CPU threads for compilation, virtualization or video encoding will benefit from the 16-core configuration and large memory pool. The single RTX 5070 with 12GB VRAM limits users who need dual-GPU scaling or larger frame buffers for 3D rendering. The 10TB mechanical drive serves bulk storage, but professionals wanting all-flash arrays should look at alternative configurations.

The tower ships with the Ryzen 9 9950X, 128GB DDR5, 1TB Samsung 990 PRO SSD, 10TB HDD, RTX 5070 12GB, 360mm liquid cooler, 850W PSU, Windows 11 Pro and Wi-Fi 7. No screen, keyboard or mouse are included.
128GB DDR5 fills all four slots on the X870 EAGLE motherboard. The 192GB maximum would require replacing modules, so the factory 128GB is the simplest high-capacity choice.
The 16-core 32-thread CPU can hit 5.70GHz on light loads, while the 360mm liquid cooler keeps temperatures low enough to sustain high clocks during extended gaming sessions.
