I have a 21in iMac (the model right before the aluminum one) in great working condition, it is loaded with Logic Pro and Final Cut Pro (it was part of my studio for the duration of its ownership)
It was my income provider so it is in great like new condition. I would sell it for $750 and I wont uninstall any of the pro software, which is worth more than the price i am selling the computer for.
