Target Build

This liquid-cooled gaming desktop ships with a 24-core Intel Core Ultra 9 285K processor and an Nvidia GeForce RTX 5090 graphics card with 32GB of video memory. It includes 32GB of DDR5 system memory, a 1TB Samsung 990 PRO NVMe SSD and a 10TB hard drive with 256MB cache. Windows 11 Pro 64-bit is pre-installed.

Setup Check

The system arrives fully assembled inside a Corsair 4000D Series tempered-glass tower measuring 490 x 239 x 486 mm. Rear I/O provides one USB4 Type-C port, one USB 3.2 Gen 2 port, four USB 3.2 Gen 1 ports and four USB 2.0 ports. Network connectivity includes Intel 2.5Gb Ethernet and Wi-Fi 6E AX211 with Bluetooth 5.3. A 1200W 80 PLUS Gold power supply is installed.

Bundled Impact

The 360mm quiet-edition AIO cooler handles the CPU thermal load without high fan noise. Four M.2 slots and four SATA 6Gb/s ports on the Gigabyte Z890 UD motherboard allow RAID 0, 1, 5 or 10 arrays for future storage expansion. Realtek 7.1 surround audio and the pre-loaded Windows 11 Pro environment are ready for immediate use.
