Budget cpu and motherboard

[OMNI_VolTage]

About 5 months ago I got a $100 PC because I needed one, and it's doing its job but it's a $100 PC, it's has a crappy Intel dual core processor, and a motherboard that is case specific.
The hard drive could use some extra space but I made due, and it has 8gb of RAM so that's fine.
What I'm looking for is a case, motherboard, and could that is budget but will do what I need it to, I am a video recorder and editor, so I would like a quad core cpu that I can use fine with Elgato recording software, Sony Vegas, and After effects.
