Questions about this item

Will my existing ATX motherboard and 360 mm top radiator fit in the Lanjie A31?

The case supports ATX boards and a top mount for 360 mm radiators, so both will fit.

How do I confirm the front USB 3.2 Gen 2 Type-C port is running at 10 Gbps after building?

Check the OS device manager or BIOS USB section; it should report a 10 Gbps SuperSpeed connection for that port.

Does the box include any fans or a power supply, or do I need to buy them separately?

No fans or power supply are included; you must purchase a PSU up to 200 mm long and any 120 mm or 140 mm fans you want.
