Liquid-cooled desktop with a 24-core Intel Core Ultra 9 285K, 192GB DDR5 and a 2TB NVMe SSD running Windows 11 Pro
This desktop arrives fully assembled with Windows 11 Pro installed and a 24-core Intel Core Ultra 9 285K processor at its heart. It targets enthusiasts who want high multi-threaded performance for gaming and content creation without building the system themselves. The 192GB DDR5 memory and 2TB NVMe SSD provide ample capacity for large projects and fast load times. Buyers who need a dedicated graphics card for ray tracing or high-refresh 4K gaming should look elsewhere.
A 360mm liquid cooler handles the CPU thermal load inside a Ceres 300 tempered-glass mid-tower with front and rear 140mm fans. The front panel offers USB 3.2 Gen 2 Type-C, two USB 3.0 ports and HD audio for daily peripherals. Rear I/O includes Thunderbolt 4, USB 20Gbps and 10Gbps Type-C, multiple USB 5Gbps and 2.0 ports, HDMI, DisplayPort, 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4. Four M.2 slots and four SATA 6Gb/s ports allow future storage expansion inside the case.
Verify that your monitors use HDMI or DisplayPort inputs to match the integrated graphics outputs. Confirm the 475mm depth, 245mm width and 463mm height fit your desk or floor space. The 850W 80 PLUS Bronze power supply uses standard ATX cabling for the motherboard and components. Ensure any additional drives you plan to add are SATA or M.2 NVMe form factors supported by the four onboard M.2 connectors.

The case measures 475 mm deep, 245 mm wide and 463 mm high; the front-mounted 360 mm radiator fits behind the two 140 mm intake fans.
Align the notches, lower the CPU gently, then close the retention lever fully — skipping the lever lock leaves the chip unseated.
