A liquid-cooled tower with a 16-core Ryzen 9 9950X, 64GB DDR5, 1TB NVMe, 10TB HDD and Radeon RX 9070 XT for high-end gaming and media work
This desktop ships as a complete tower system built around a 16-core AMD Ryzen 9 9950X processor and a Radeon RX 9070 XT graphics card with 12GB of video memory. It includes 64GB of DDR5 memory, a 1TB NVMe SSD and a 10TB hard drive, all cooled by a 360mm liquid cooler and powered by an 850W supply. Windows 11 Pro is pre-installed.
The configuration suits creators and enthusiasts who need high core counts for rendering, simulation or heavy multitasking alongside modern 1440p or 4K gaming. Buyers who require ECC memory, dual-GPU support or more than four memory slots should consider alternative platforms. The single 1TB NVMe drive may also limit users with massive active project libraries.
The 1TB NVMe drive delivers read speeds up to 7450 MB/sec and write speeds up to 6900 MB/sec for the operating system and active applications. The 10TB hard drive adds deep bulk capacity for media archives and backups. Four memory slots support up to 192GB of DDR5, providing headroom for future memory expansion beyond the installed 64GB.

The motherboard provides four DDR5 slots in total and the system ships with 64 GB installed. It supports up to 192 GB, so additional modules can be added without removing the existing ones.
Yes. The board includes two SATA 6 Gb/s ports and the case has two internal 3.5-inch bays, so legacy SATA drives can be connected and mounted alongside the NVMe SSD and 10 TB HDD.
The 360 mm AIO uses a 140 mm fan; listen for its low-noise spin and check the pump RPM in BIOS or the supplied monitoring software. CPU temperatures under load should stay well below the 5.70 GHz boost threshold.
