I bought a 233mhz Rev. A iMac with a blown video board. Here is the result of putting the iMac internals into a PC mini tower case. It's shown running System 10.1 on the external Apple monitor. The iBox has a 20 gig hard drive and 288 megs of RAM. The computer is used as a backup server for client computers. There are three lights on the front, red, yellow, green to go along with System 10. The idea behind this was to do it as cheaply and simply as possible. The PC case was purchased at a local Goodwill store for $1.98.
This simple case hack was done using spare parts found in my garage and by no means do I consider it to be high quality hack. I used the iMac power supply and just bolted it inside the case as shown from this top view photo. The fan shown is one of two, the other is in the front of the case. It runs 24 hours a day and the processor doesn't get as hot as it did in the iMac case.
Here's a view of the mount for the iMac logic board and external video connector. The power button on the front of the case is wired into the iMac power button and the iMac speakers are mounted to the bottom of the case. Power for the three lights on the front of the case is taken from the power connector for the hard drive.
Here's a view from the back. I consider it a crude hack but it gets the job done and allows the iMac to live again.
Here's a pix of an early prototype to see how everything would fit and to determine what I could leave out. I found a CD ribbon cable that would allow me to mount the CD drive in the front of the case. Cutting out the mount for the CD bezel was the hardest part of this simple case hack.
