i have 3 pc's...

1. Dell dim 2400, Celeron 2.4GHz 256MB ram 40gigHD Win-XP
2. Dell dim 8100, Pentium4 1.4GHz 128MB ram 40gigHD Win-Me nVidia vid-exel.
3. Packard Bell platinum surpreme 1952, Pentium2 266MHz 64MB ram 6.4gigHD Win-95

i currently use the 2400 with the win-xp

i always see pictures with several pc towers, monitors together in use...

how can i use these other pc's to my advantage?

in what way can i connect them to use them, besides networking, so they are not just collecting dust? or is plain networking the way to go?

what's the best config.

i guess this question is for the GURU's...
