This guy's parents gave him a dual-CPU Mac G5 for Christmas, which wouldn't run any of his Windows apps, so he gutted the box and installed the guts of a PC, then donated the Mac parts to a friend who is going to try to jam them into his old G3 chassis.
It's a good thing my parents don't know anything about computers, because I'm sure they would be really angry if they knew what I did. I have to say that I'm happy – I can keep on using XP.
The board is a Biostar Micro ATX, with a 2200 Athlon XP with an Adaptec 29160 SCSI controller and two 36 GB Atlas 10K V hard drives. I am stuck using the onboard video because there is no AGP slot. I had no money for a SATA controller and quite honestly, I swear by SCSI (the G5 comes with SATA drives).
Update: Looks like this is a hoax
