I just got my HAF 922 last week...its massive for a mid tower...at least in comparison to my 5 year old Antec 900. I looked at just about any case I could find prior to ordering the 922. Loads of room for even the longest vid cards. Lots of options for air flow and plenty of room for running wires out of sight.
If you need a case that you will be carrying often then look for some quality handles on top. The CM Storm range will do it for you. Under 100$ there is the Storm Scout. Under 150$ the Storm Sniper is an excellent case.
