Built for heavy compute

This system ships as a complete mid-tower desktop running Windows 11 Pro. A 24-core Intel Core Ultra 9 285K processor, 128GB of DDR5 memory and an Nvidia GeForce RTX 5080 16GB graphics card sit on a Gigabyte Z890 UD motherboard. A 360mm liquid cooler and a 1000W 80 PLUS Gold power supply handle thermals and delivery. The 4TB Samsung 990 PRO NVMe drive provides primary storage.

Verify your workspace

The Corsair 4000D chassis measures 490mm deep, 239mm wide and 486mm high so confirm desk or rack clearance before ordering. Rear I/O includes 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 plus Intel 2.5Gb Ethernet and Wi-Fi 6E with Bluetooth 5.3. Internal bays offer two 3.5-inch and two 2.5-inch slots while the board provides four M.2 connectors and four SATA 6Gb/s ports for future expansion.

Suits single-box AI and render work

Buyers who need a ready-to-run platform for modelling, editing or local AI inference with 128GB of unified system memory and a modern GPU will match this configuration. The four memory slots are fully populated so anyone planning to exceed 128GB must replace modules rather than add them. Users who require multiple graphics cards, ECC memory or a larger storage array out of the box should look at a different platform.

Questions about this item

Does the 128GB DDR5 memory fill all four slots or leave room to add more later?

The system ships with 128GB DDR5 installed across four slots; the motherboard supports up to 192GB total so an upgrade would require replacing modules.

The spec lists a 4TB Samsung 990 PRO — is that the only drive bay used or are the 3.5 inch bays still free?

The 4TB Samsung 990 PRO occupies one M.2 slot; the case still provides two internal 3.5 inch bays and two 2.5 inch bays for additional storage.

The RTX 5080 has 16GB of video memory — will that be enough for 4K rendering workloads?

The 16GB frame buffer on the RTX 5080 handles 4K gaming and many GPU-accelerated render tasks; extremely large scenes may still spill to system memory.
