It is amazing what people will pick up on. The first time I looked at the page I completely missed it. One of the interesting things to note is 8 gigs of RAM max, this means that they are using the 64 bit IBM 970. For reasons I won't claim to understand, the max allowable by a 32 bit processor in a conventional machine is 4 gigs (and I'm not certain if Mac OS X 10.2 can even see more than 2 gigs).
