Upgrading Mobo in HP case

[Bassticular]

Okay, I have an older HP Pavilion m8277c. I want to upgrade it for gaming performance. I've checked many specs and dimensions and basically need to know of any major problems that I might encounter. I plan to get the Gigabyte GA-78LMTusb3 mobo. With the FX-6350 CPU 8gb of Ram and a EVGA 500B psu. I plan to reuse some old parts. All the measurements on both mobos are the same. Will this work?

This is the wiring diagram for the HP motherboard.

The case doesn't look like it has very good cooling. The two motherboards are both MicroATX size. I would recommend using a $30 - 40 bare pc case. A Mini-tower case fits MicroATX size and Mid-tower fits both MicroATX and ATX size motherboards.

Yeah I figured the airflow would be a problem. I will check out a bare case. One more question. Will that psu support both that mobo and CPU?
