The Satechi Mac mini Stand & Hub sits under a Mac mini and adds front-facing ports plus a built-in enclosure for an NVMe SSD, so you can expand storage without extra clutter.

Key features:

Add up to 4 TB of storage with an M.2 NVMe SSD in 2230, 2242, 2260 or 2280 size.
Transfer at up to 10 Gbps through the enclosure and USB-A 3.2 ports.
Plug in from the front, including USB-A ports for older devices.
Reach the Mac mini's power button through an opening at the back.
Keep the SSD from overheating with a thermal pad, plus bottom vents for airflow.
Tidy cables with built-in cable management in an aluminum body.

The hub matches the M4 Mac mini design (the current listing also names M5 Pro and M6) and does not fit M1 or M2 Mac minis. SATA SSDs, drives with heatsinks and double-sided drives are not supported, and no SSD is included. It costs $99.99 with a two-year warranty.
