Cases come in 3 main sizes. Full, Mid and Small form factor. You want a Mid tower case. Mid towers can fit multiple expansion cards (normally 7) and ATX form factor motherboards.
ATX form factor is a size of motherboard, this is the most widely used size for enthusiast PC systems.
the amount of ram you've been mentioning is not needed, the MAX you want is 12GB, any more is a waste, you also want a Dedicated graphics card.
Give me a budget, and ill piece a system together for you, appropriate for editing.

12GB @ 1333Mhz = a lot. Are you editing these videos? by the looks of things you can't keep focused on one thing for more than a day, can you really do long edits without getting fed up?
