aha i didnt think of that!
I've only got two boxes running at the moment (though might be 3 soon as the replacement
psu's from dell finally turned up for my laptop this morning. only took them a year!)
The two boxes are an intel p4 n/w c 2.4 @ 3 with 1gb of ram (running two instances) and a banias 1.6 with 512 ram
