Computer Tech: Why a Mac?

DIY arcade game from a Mac G4 - Engadget - www.engadget.com: "People find many creative ways of repurposing their old machines, though few are quite as creative as creativebastard, who spent a full year converting his old dual 500MHz Mac G4 into a classic arcade-style gamebox. Can�t beat that canary yellow, nohow."

So why would you do this with a Mac when you can do it much cheaper with a PC? The parts are all out there and frankly the PC itself has got to be cheaper. It won't be any more stable running arcade emulators, it's not easier to mod (in fact it would be harder to mod). Some people need to let their Mac obssesion go and use a PC when there's no reason for a mac.
