I have a problem. I recently got a Dell optiplex 780. I have an Msi afterburner 560 graphics card and it cant fit in my case. So I need to get a new case. Is there anybody who can tell me what case will fit my motherboard? Does it matter? Please help!

BTX case sucks, there are no replacement for that case, I been looking for this sometime ago and could not find one.

This little guide explains the "fit" issue.

THIS POST APPLICABLE TO MT (MINI TOWER) FORM FACTOR ONLY.

Unfortunately no card that is more than 7.5 inches long or 2 slots wide will PHYSICALLY FIT inside the case - it was found that only single bracket video card can fit due to BTX MOBO, where card internals facing upward towards PC internals, not ATX, where dual card design is blocking another PCI slot by facing downward.
If you prefer the card with beefier fan, then the length of the card must not exceed 7.5 inches, otherwise only "skinny" single bracket, single slot cards can physically fit.

its hard to tell. I know the 780 case is a btx case. I don't know if you can find a case for that motherboard. your going to need a two slot card and then its going to run warmer since it will be pinned right against the bottom of the case.

Pictures below will prove my point.

View shows no room for dual bracket

Single bracket only, or you have to cut dual bracket in half

This is the other way to show my point

Here you can clearly see only single place for the bracket

7.5 inches explained, also shown "obstacles"

This is the picture of actual "skinny" single slot video card (not sure which model)- perfect, "glove" fit.

So if you have dual card you pretty much in deep troubles. Single slot with massive cooler might fit after serious case modification.

Anything else I can help you with?

See the problem is when you get graphics cards is you need to make shure that you get a SLIM FIT. Sometimes graphic cards come with extra brackets, and that you can move the cables around to ajust to what you have.
