Questions about this item

Will my existing SATA SSDs and 3.5-inch hard drives fit inside the Corsair 4000D case alongside the installed 10TB drive?

The case provides two internal 3.5-inch bays and two 2.5-inch bays. The motherboard also includes four SATA 6Gb/s ports that support RAID 0, 1, 5 and 10 for additional drives.

How can I verify the liquid cooler is running correctly after I power on the system?

The 360mm Quiet Edition AIO uses a 140mm fan. Check that the fan spins, listen for pump noise, and monitor CPU temperatures in BIOS or Windows — the Core Ultra 9 285K should idle well below its 5.70 GHz boost ceiling.

Which cables and accessories are included in the box, and what must I supply myself?

The desktop ships with Windows 11 Pro installed, the Corsair 4000D case, 1200W 80 PLUS Gold PSU, 360mm liquid cooler, 32GB DDR5, 4TB Samsung 990 PRO SSD, 10TB HDD and RTX 5090 32GB GPU. You only need to provide a monitor, keyboard and mouse.
