A liquid-cooled gaming desktop with a 24-core Intel Core Ultra 9 285K, 128GB DDR5 memory, 1TB NVMe SSD and GeForce RTX 5060 Ti graphics
This desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and a 1TB NVMe SSD. Liquid cooling handles the CPU thermal load in a tower form factor. The system ships with Windows 11 Pro installed and is marketed as AI ready for local workloads.
The Corsair 4000D chassis provides tempered glass panels and internal bays for two 3.5-inch and two 2.5-inch drives. Front I/O includes one USB 3.2 Type-C port and two USB 3.2 Gen1 ports alongside an audio combo jack. Rear motherboard I/O adds a USB4 Type-C port, one USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 ports. Networking uses Intel 2.5Gb Ethernet with Wi-Fi 6E and Bluetooth 5.3.
The installed GeForce RTX 5060 Ti carries 8GB of video memory, which caps texture capacity at 4K or heavy ray-tracing settings. The 850W 80 PLUS Bronze power supply delivers overhead for the current build but leaves little margin for a significantly larger GPU upgrade. Maximum system memory supported by the motherboard is 192GB across four slots.

The Z890 UD motherboard provides a PCIe 4.0 x4 M.2 slot; the Samsung 990 PRO reaches up to 7450 MB/s sequential read on that interface.
The Corsair 4000D measures 490 x 239 x 486 mm and includes two 3.5" and two 2.5" internal bays; the 360 mm AIO mounts in the top or front.
Populate the two primary slots first (usually A2 and B2) for dual-channel; filling all four slots out of order can prevent the system from posting.
