Are these items compatible with my motherboard

[Daniel_113]

I have a 0m863n motherboard from the Optiplex 760 PC. I'm planning on upgrading my computer. Can any of these connect to my motherboard? Or actleast does my motherboard have the correct connection points?

Also will my motherboard fit in one of these (or is it too small)

This is my first time asking here so apologies if I got something wrong or it's in the wrong category.

Everything will fit and work.

Four different sizes
1)MINI TOWER
2)DESKTOP
3)SMALL FORM FACTOR
4)ULTRA SMALL FORM FACTOR

It appears the first two wouldn't fit the bare ATX mid-tower cases because they use an obsolete BTX form factor design. Since your part number corresponds with the SFF motherboard, the answer is here is also no. That is a custom Dell design for its SFF case.

So if I got a new motherboard, will I be able to transfer my Ram and Hard drive onto that one? I have DDR2 Ram
