I guess it has been said many times before on this forum, but I have to praise this machine again: it is insane that this iMac from 2007 still runs as good as it does. in the last weeks I "reactivated" this machine after I gave it to my son for 1,5 years (but he rarely used). I did a clean install of OS X and Boot Camp and was delighted about the results. it still runs the latest Mac OS X and with some tricks it even runs Windows 10 64 bit with Boot Camp. with 6 GB of RAM and still the old 320 GB HDD it serves me very well with OS X and Windows. and the design is timeless. like it more than the current iMac Design. I hope some guys of you out there also still enjoy this machine!
