We'd like to think of this as a "Mac hobbyist iMac!"
The main reason is that this iMac is a 2008 model and is no longer being supported by Apple. You can still install Chrome and Firefox, but Safari and the Operating System will no longer be receiving updates — including security updates — from Apple. We wouldn't trust this to be your "everyday usage" computer.
However, if you understand those implications OR you want to use this as something that never touches the public Internet, these are still fantastic computers! And you just can't beat those Apple screens!
