anyone ever run across info about building a custom kiosk like setup?

i have been noodling an idea for a real estate company - to be able to set up a kiosk in local highly populated area.

here are the design specs:
  • durability - initial thoughts are to have a 17" lcd behind lexan or something like that, with the computer down below.
  • power (need to consider power options if i dont have a nearby plug)
  • security - through cheapness (not the end of the world if it gets ripped off) and simple vandalism prevention
  • internet access. 2 options - a local last mile isp (clearwire) or just use a sprint broadband phone/cable card
would love to hear thoughts or see any links people might have come across.
