Beige G3 RAM and PSU questions:

[Trash80toHP_Mini]

The pinout is compatible with 20 pin ATX. The tower PSU is basically an ATX PSU. The desktop one has the soft power the Mac way instead of the ATX way, so if you want to use a board out of a desktop with ATX you have to swap Jumper J28 over to the other position (it's in the corner near the back of the end PCI slot.

Nice, thanks much for that info. The little 1U compatible 300w PSU arrives today from Amazon. The 500w PSU arrived from eBay and it's a 9" deep freakin' beast of a thing! Wouldn't even fit nicely in the 4U PEx project.

It's only got ten SATA power connectors aside from Molex aarray.
