The PC-7 does have some nice features. The only one that I wish would have carried over to the PC-65 would be the rear 120mm fan, or at least the addition of a second 80mm fan on the back somewhere. The dual front 80's work great however, tiz the same setup on the PC-75 which I used to have and can vouch for the amount of air those 2 fans push from up front. The PC-65 also comes with the top exhaust fan which the PC-7 does not. And of course the two biggest selling points would be the removable mobo tray and the included side window.
