If there is someone here extremely rich, I want them to do this... Buy about 500 of these things... Then get a big 'supercomputer' room, like where you always see massive computers housed. Then, just make an aisle with 250 servers on each side... That would look impressive... Even more impressive than a bunch of dells. They would look like space-age computers...
I wonder if they'll do clustering, and if so, how would they connect? I know that there are ways to setup a render farm over a network, but if you could daisy-chain these suckers together with a special, high bandwidth cable coming from a PCI card, that would totally kick @$$ And if they had up to 4 processers each, the scenario above would have 2000 G4 processors!!!! Of course, I don't think clustering would support that many, but just the thought of it is cool...
PS, after whoever it is that can accomplish this scenario, just remember to think of the guy who gave you the idea when you're looking for something to do with some of those servers...
