I have told someone this before, it might have even been you idk.
Buying a case is NOT PERSONAL PREFERENCE!!!!
When buying a case:
~Look for the case material. different materials disipate heat different than others.
~look for form factor (ATX, mATX ext.)
~Look for size. some people want full towers. Full towers are pretty big but have overall good airflow and room inside the comp where as mid towers have good enough size but a little decreased airflow.
~Make sure the case has enough fans and room for all your optical drives and hdd's.
~PSU's also have to fit in these so make so you have the right size psu as well
cases are not personal preference.
