I got this case through Amazon from a company called Computer Geeks, I hate trying to use Ebay for anything I really want unless there is a buy it now option and it is reasonable. I manage to get a lot of stuff off Amazon for pennies plus cheap shipping as well.
I use something called Kijiji which is like craigslist since I have bought an iMac G3 off of it and I got a PowerMac G3 full package (monitor, keyboard and mouse) in return for a Nintendo DS original that i bought off of a friend for $8 and never used.
