Dell Optiplex 745 - Tower -> Desktop

[Kelemvor]

So, I have an Optiplex 745 mini tower that I use for my HTPC. We have a new shelf and this case is a bit too large to fit well where it's going to be located.

I'd rather not have to buy a whole new computer and thought maybe I can take the internal components and put them in a different style of Optiplex 745 case. Anyone know if they are compatible or if the tower version has larger components and won't fit in the other styles?

I haven't been able to find anything specific online so far...

Thanks.
