Ready-to-game desktop

This tower ships with Windows 11 Pro installed and an eight-core AMD Ryzen 7 9800X3D processor at 4.7 GHz with a 240 mm liquid cooler. The 192 GB DDR5 memory and 1 TB Samsung 990 PRO NVMe drive are already configured for immediate use.

Quiet liquid cooling and front I/O

A 240 mm quiet-edition AIO keeps the CPU temperatures low while two 140 mm PWM front fans move air through the tempered-glass case. The front panel offers a USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and a 3.5 mm audio jack for daily peripherals.

Integrated graphics only

The system relies on AMD Radeon integrated graphics driven through HDMI and two USB4 outputs, so no discrete GPU is included. Buyers who need dedicated 3D performance for modern titles or GPU compute workloads will have to add a graphics card themselves.

Questions about this item

What USB4 speed does the rear panel support?

The rear panel includes two USB4 ports rated at 40 Gbps each, using USB Type-C connectors.

What case clearance is required for the 240 mm liquid cooler?

The tower case measures 447 mm deep, 215 mm wide and 469 mm high, with front mounts for two 140 mm fans that hold the 240 mm radiator.

How is the 192 GB DDR5 kit installed across the four slots?

Populate all four DIMM slots with the matched modules; the common mistake is leaving a slot empty or mixing kits, which prevents the system from reaching the full 192 GB capacity.
