I only have ordinary Apple hardware.
PowerMac B&W G3 300MHz (1999)
PowerBook FireWire G3 400MHz (2000)
Cube G4 450MHz (2000)
PowerMac Quicksilver G4 733MHz (2001)
PowerBook G4 12" 1.5GHz (2005)
The Pismo has a faulty hard drive as it seems and the Quicksilver has a faulty PSU.
On both PowerBooks I will install VoidLinux. Shouldn't be a problem for both.
The only Macs that are problematic are eMacs and iMacs. Both have a CRT without EDID support.
I also have had a PowerMac Quad G5 (Late 2005, PCIe) and now I have a Blackbird.
@ClassicHasClass: Which OS are you running on the BeBox?
BeOS 5?
