Will this case fit a new motherboard?



Unfortunately Optiplex 960 has BTX motherboard, not ATX

This is how it is looks, got it from here http://www.txcesssurplus.com/servlet/the-6014/Dell-F428D-Socket-775/Detail

So the answer is no, it is not going to work, sorry.

Anything else I can help you with?
