Hey everyone! i have finally done it! i have modded and old Power Mac G3 case to fit a modern System! anyway, lets get started with the build log itself! 
I gutted the system.

mobo tray
after gutting it, i took a while to ponder how i was going to add the motherboard standoffs,because the original ones were in non-standard positions. i ended up deciding to drill through the side panel and use a bolt and nuts.

Time for the system to come out of the old case!

well, that's it for now, even though the system is done, i still have yet to take pics of it all installed and working.
