Get a KVM switch and a second low end box for web browsing with Linux....
Back in 98 or so I used to do that using the Red Hat box to allow both machines (Win 98) using NAT to surf. There was a an IP tables modification on the web that you could copy. I was lucky enough to have an early enough installation of Verizon DSL, so they gave me a static IP. They took that away a few years later.
