PowerMac G3...mother board question.

[G51989]

So, I only ask around here because I can't seem to find any info on it via google, will a miniATX motherboard fit in a PowerMacG3 Case? I picked up a blue and clear case, the computer I picked up, doesn't actually work.

But, I have a Sempron 3100+, 2 gigs of ram, Radeon HD 4200 somthing, standard ATX power supply, on a miniATX motherboard, the type with an AGP and 3 PCi slots.

Question is, will this thing fit easily into one of those cases?

I'm sure you can do it. You'll have to drill your own standoffs though and probably do some makeshift work for the PSU to fit as well.
