Proxy Server for Internet Cafee

Can you guide to the best hardware specification for a Proxy Server?
Is Windows 2000 and Proxy 2.0 + Patch are too good for a Proxy Server?
Is Dual Dialup modem is good as Leas line, how dose Dual Dialup Modem work?
How dose the new connection using my TV Satellite, Receiver, A Channel and a Server to run a Proxy Sever with Hi-Band width connection?

Thanking you,
