I've been considering setting up a Debian server to run OwnCloud for awhile, and am considering using my (currently unsused) iBook G4 for the job. It's the 1GHz 12" model (https://everymac.com/systems/apple/ibook/specs/ibook_g4_1.0_12.html). I remember reading somewhere that this model partially cools through the keyboard. Of course, that could have been wrong, or I could be misremembering. My question is then, can I safely leave this model turned on 24/7 with it closed without worrying about overheating? Also, anyone else tried using an iBook in this manner with any potential caveats to note?
