Sounds like a nice system. And you get the benefit of having the store close by (well, within the same state at least, anyway!), so warranty issues are not so much of a prob, if they arise.
I've dealt with eyo.com.au before, but felt the service and advice form PCMarket was a bit better. Maybe because they are not mainly resellers, but an IT company that does parts on the side for enthusiasts.
Have fun with your new system. Gonna put a DC on it??
