Good Mach I case?

I recently bought a Mach I Phase Change unit second hand from chiyau (:rockon: ) and fitted it into my Chieftec Alumminium Dragon.
Only problem was, the Alumminium Dragon is slightly taller than most ATX cases (not full tower) so the motherboard is placed higher up in the case.

This caused the hose of the Mach I to snap as it was over streched, which means I now have to pay £100 to get it regassed, re oiled and the hose repaired :rant:

I also want a new case as my aluminium dragon is too big, anyone know what sort of case I should be looking for. Nothing fancy as this system is only used for LAN round my house.

Anybody?
Cheers
