Questions about this item

What clearance does the 65W power supply need for the Mini PC's ventilation?

The ultra-small form factor fits under a desk or behind a monitor; keep the side and rear vents unobstructed so the 65W supply can dissipate heat.

Which screw secures the M.2 NVMe drive during installation, and where is it located?

A single M.2 standoff screw on the motherboard holds the 512GB NVMe SSD; insert the drive at an angle, press down, then tighten that screw.

When the 16GB DDR5 memory reaches 64GB maximum, which slots do I populate first?

The board has two DDR5 SO-DIMM slots; fill both for dual-channel performance up to the 64GB limit.
