Buying a server..

[Shadowhawk]

Hi, not entirely sure if this is the right place for this thread...anyway.

I'm looking to buy a server (Obviously), for hosting websites, with an eye to exchanging space on the server for money.

Basically:

What would you suggest for such a server? (I had a glance at IBM's BladeServers, merely because they advertise them)
What connection type would I need? (And possible cost of said connection/installation)
What sort of income should I be expecting (If any)?

Is this a viable plan?

Thanks,

Shadowhawk.
