The 990 model relies on the Q67 chipset, which only works with Sandy Bridge processors. For Ivy Bridge CPUs, use an Optiplex 3010, 7010 or 9010.

Yes, you could purchase only the motherboard from one of those options and replace it with the one in your 990.

From an electrical standpoint it might function, but the rear port design has shifted which means you’ll need to handle some metal adjustments. Could you share your budget and list the components you currently possess?

Your system should work with the Dell 990 and 32GB RAM. The 3770 processor is compatible with these components.
