Building a mini cluster, Help?

[aaa801]

Hi guys,
ive recently managed to get a lot of duel core pcs from a couple years ago (10 desktops)
i was thinking about turning them into a cluster in my room (mwuhahaha free electric)

I was thinking about using vnc servers on them all for setting them up when there working, and linking them to a switch,
my internet to my main pc is from a usb wifi connection so is it possible to bridge these connections? eg wifi and eathernet so that the cluster has internet too
Will be running backtrack on all the cluster pcs,
So does anyone know any decent ways to do this?

i do not have a router
its a hotspot in the hostel im in (included with rent)
so if i connected a eathernet from the main rig to the switch
and bridged the connections would it work

ok thanks,
would that require any extra configuration on the linux end?

Mostly password cracking / rainbow table generation
Proberly lob a couple cuda cards in each of them once the mobos replaced
or just run seti in downtime
