I stumbled upon this site that has all these old case mods from around the year 2000. It looks like the site is relativly large, but hasn't been updated for years. Its like stepping back in time. A lot of them have homemade fan controlers with toogle switches. Anyways I thought it was interesting and that you guys might too. They start getting interesting 3 pages in (#47).

Here's the link
