Which mini PCs it fits

The dock connects over Thunderbolt 5, so the machine needs a USB4 or Thunderbolt port. The GMKtec M8, HP Z2 Mini G1a and MINISFORUM AI X1 Pro fit with a caveat: each connects through a USB-C port, but runs the dock at 40 Gbps on its USB4 port, not 80. The Beelink EQR6, Dell Pro Max Micro FCM2250 and GMKtec G11 Plus do not fit, because none has a USB4 or Thunderbolt port. For the GMKtec NucBox G3 and MINISFORUM AtomMan G1 Pro, we have not confirmed the fit, as we have no details of their USB4 ports.

Checked against every mini PC sold on amazon.co.uk, from the specifications we hold for each machine.
