iMacQuariums for sale in Items For Sale Posted April 20, 2011 The first photo there looks brilliant, glad to see you're still doing them! Where you source your cases from, may I ask? I buy dead iMacs from local electronics recyclers. They usually have a whole warehouse full of PC's with a small batch of macs on one or two pallets tucked in the corner. Often it is hard to find them in good enough condition to build into aquariums out of.
