I've always been impressed with how solid IBM's hardware is. Anyway, one thing you might look at is to see what's running, and if you don't need it, turn it off, and maybe uninstall. If these are PoS boxen, do you need X windows? Do you need Gnome or KDE as windonw managers (look at smaller ones - I use IceWM at home, < 600k, yes, k, not M; the other admin here likes xfce)? mark
