DON'T use an MY switch based keyboard unless you already have one laying around waiting to be gotten rid of.
I tried a Rush card back when they were new. I took it back to the store a couple days later and got a Banshee instead. Then I got a Voodoo 3 not too long after that.
My idea of a Rush troll PC would be something with the best stuff from that period and a case with a huge 3dfx logo on the side and maybe some other 3dfx themed stuff on the case, desktop wallpaper, etc.
Then you have the Rush installed so when people go to play it, that are like... #%$%$&%^** this is crap and then you tell them it has a Voodoo Rush in it and then you have another setup with the same hardware in a plain case except for the video card, which you have dual V2 12MB, a Voodoo 3 3000 or 3500, or Voodoo 5 5500 installed so they can then be wow'd at the awesomeness.
