Verify that your workspace can accommodate a case measuring 469mm deep by 220mm wide by 490mm high. The motherboard offers four M.2 slots and two SATA ports for additional drives. Rear I/O includes two USB4 ports, one USB 10Gbps port, three USB 5Gbps ports and four USB 2.0 ports. Front-panel connectivity provides two USB 3.0 ports, one USB 3.2 Gen 2 Type-C port and audio jacks.

Ideal buyer

Suits professionals who need 192GB of memory for large modelling, rendering or AI workloads and want a liquid-cooled 12-core CPU with a 32GB GPU. Not for buyers who need more than 192GB of RAM, who require multiple graphics cards, who want mechanical hard-drive bays beyond the two 3.5-inch mounts, or who need an optical drive.

Questions about this item

Does the PC ship with a keyboard and mouse or do I need to buy them separately?

The system includes the tower with all internal components, Windows 11 Pro and a 240 mm liquid cooler; no keyboard, mouse or monitor are supplied.

Should I choose the 192 GB DDR5 option or is a smaller capacity available for this build?

The motherboard has four slots and supports a maximum of 192 GB, so this configuration already uses the full capacity the board can accept.

What does the 7450 MB/s read speed of the Samsung 990 PRO mean when the machine is running real workloads?

It is the peak sequential read rate over the PCIe 4.0 x4 link; actual application performance will be lower depending on file size, queue depth and thermal conditions.
