I was wondering if i could put an am3+ motherboard in my dell optiplex 745 desktop, and take out the dell stock motherboard? I want to put an amd eight core processor in my computer but the dell socket for cpu is lga 775. Please help and comment and tell me if i can.

The Dell OptiPlex 745 Desktop uses the obsolete and discontinued BTX form factor (i.e. Intel cancelled all BTX product development in September 2006).

An ATX form factor motherboard will not fit in the Dell OptiPlex 745 Desktop's case. Then there's the old BTX power supply that won't support the new ATX motherboard.

So the answer is a big NO.

If you get a new case, you can try and salvage as much as you can from the old system, but it won't be much.

Any new mid-tower case you buy will have an ATX form factor so the current BTX motherboard will not be able to be mounted into that case because the expansion slots and rear panel I/O connectors on the BTX motherboard are not in the same location as for the ATX form factor. The BTX power supply won't mount properly either.

You're essentially building a completely new system anyway so it's best to wait until you can afford all of the components to do it properly.
