I guess I really don't get that. The rear USB ports are less than a foot from the front panel and make for a clean appearance when utilized... Front USB is 'nice to have' not 'need to have' and to sacrifice a clean look so you can have 4+ of them doesn't seem like a worthwhile trade IMHO.
Ive got some plans of setting computer in shelf, where there is little chance of putting any USB behind the case without actually taking the whole case off from the shelf.
Anyhow, even on desk i dont like raising my lazy butt to reach behind my case and just rather use the front usbs. Sure i could buy external hub - but that is more clutter which i couldnt want less.
So atleast i am "function over form" -sort of person, but this is ofcourse totally personal preference.
