First off i'd like to clarify something so we can stick to the point in hand.
A Tooless Case is;
A case that requires no tools to fit components in the expansion slots and/or the drive bays. IE....after the motherboard,cpu,psu an fans have been fitted.
With that said, this is what I recommend.
COOLERMASTER !
I have been using a Centurion 5 case at work for the last year or so and I cannot fault it. It doesn't have the removable m/board tray you're after though.

The best option for you would be to go for the Preatorian, 731 or 732. As far as looks go this has got to be one of the most stylish cases i've seen. And it's aluminium (no thats not a typo, i'm English!
).
The motherboard tray is removable and flippable (can be mounted on the opposite side of the case).

The Centurion comes with a psu (always handy to have a spare!) but the Praetorian does not.
Hopes this helps
