I agree that comments about aluminium cases being a good heatsink are overstated - I buy aluminium for weight more than cooling properties though.
Lockable screws - Good sets available now - good suggestion!
I've just ordered an Akasa Eclipse for collection this weekend. I'm building my new rig with 4 raptors in it!!! that's why i like light cases, so I can bang loads of hardware in. The Akasa does seem to have most of the things in my list - but, as usual, certainly not all of them

...One day though...
