I recently bought an iMac G5 (17", 1.8Ghz, 1GB RAM, 160GB HDD) for 50€ and other than missing its foot rubber and having a whole lot of sticker residue, it's in very good condition. I plan to install Leopard and then open it up every so often just to look at the glorious insides: Before I proceed I have two questions. First, can anyone advise if it's okay to use 99.9% isopropanol alcohol to clean away the sticker residue? If it would dissolve/damage the plastic, is there another better way? Second, I have a spare 120GB SSD out of a 2011 MacBook Air, I recently bought a SATA adapter card. Would this work in the iMac G5, albeit at 1.5Gb/s instead of 6Gb/s? And what would I need to do about the hard drive temperature sensor?
