Hi,.....As for passive PSUs of that form factor: I don't know anything about those, but I think it's highly unlikely since the PSU will need a beefy heat sink (or have super low Power output – perhaps in the below 100W range). I don't know if you know those huge bricks that Dell uses on the bigger Alienware computers, those are much bigger than the original PSU in the AGB but deliver a lot less power than the actively cooled, 450W PSU in the AGB.
