Liquid-cooled desktop with 8-core Ryzen 7 9800X3D, 192GB DDR5, 4TB NVMe SSD and 10TB HDD
This desktop pairs an 8-core AMD Ryzen 7 9800X3D processor with 192GB of DDR5 memory, delivering the throughput needed for large datasets, virtual machines and content creation. The 4.7GHz base clock and 96MB L3 cache keep latency low across 16 threads. Integrated Radeon graphics handle display output via HDMI and two USB4 ports without a discrete card.
A 240mm liquid cooler manages CPU thermals inside an Antec P20 case that includes three 120mm front fans and dust filters on three sides. The TUF X870-PLUS motherboard exposes rear USB4 at 40Gbps, USB 10Gbps and USB 5Gbps ports plus 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4. Internal bays hold the 4TB NVMe SSD and 10TB hard drive, while four M.2 slots remain available for expansion.
The Thermaltake Smart 850W unit uses a 140mm fan and Japanese capacitors to deliver stable power under continuous load, with over-voltage, under-voltage, over-power and short-circuit protection. Liquid cooling and case airflow keep the 9800X3D near its 5.20GHz boost during long renders or compile jobs. Windows 11 Pro ships pre-installed on the Samsung 990 PRO drive, rated for 7450 MB/s reads and 6900 MB/s writes.

The CPU reaches 5.20 GHz boost with the 240 mm Quiet Edition AIO keeping temperatures in check during sustained loads.
The Thermaltake 850 W Bronze unit uses an ultra-quiet 140 mm fan, while three 120 mm front fans move air through dust filters for low background noise.
Video outputs are provided by the integrated Radeon graphics via HDMI and two USB4 ports, so no separate graphics card is required.
