Questions about this item

Does the rear USB4 Type-C port support 40 Gbps data and DisplayPort Alt Mode for a high-refresh 4K monitor?

The board provides a rear USB4 Type-C port plus one USB 3.2 Gen 2 and four USB 3.2 Gen 1 ports; the USB4 connection carries DisplayPort Alt Mode so a single cable can drive a high-refresh 4K display.

What case clearance and drive bays are required for the 360 mm liquid cooler and the 10 TB hard drive?

The Corsair 4000D chassis fits a 360 mm radiator up front and includes two 3.5-inch bays for the 10 TB drive plus two 2.5-inch bays for additional SSDs.

Which BIOS setting must be enabled so the Samsung 990 PRO SSD runs at its full PCIe 4.0 x4 speed?

Enter the Gigabyte Z890 UD BIOS, set the M.2 slot to PCIe 4.0 x4 instead of Auto, and confirm the drive appears at Gen 4 speeds before installing Windows 11 Pro.
