but im wondering since i think my original case is a micro atx, and the case im wanting is an Atx if my motherboard and al parts will fit it and be compatible ?Custom computer case?
Many different cases have slots for multi-form factors. So in your case, yes the motherboard will fit, just make sure you have the desk space for it. Although, you might have a hard time taking DELL stuff apart as they've gotten really stingy on swaping components. Therefore, I recommend for your warranty to die out or to get new components alltogether.Custom computer case?
you can get a plate that screws into the ATX holes in the case, and on the other side has the MICRO-ATX for your mobo
