Mine isnt really worth bragging about.....
I have a genius 10 meg 5 port PCI hub card in my XP machine which routes to my p233mmx linux basharound box, my girlfriends 98se machine, and then a 40m cat5 going downstairs and out the window for me to use when im comfy in my hammock with my old p75 lappy, so i can cruise the net and read ebooks out in the sunshine
Other than that, ive got a 100meg card in my machine too for using at lans.
Got some plans to get an 8 port 100 meg switch and mount it inside my case for uber-l33tness
