hehe no worries, overclocking is when you make your parts faster by upping the frequency/voltage. It's a hobby for tech people 
That site I linked shows the the motherboards available from lowest to highest.
If you only have $50 to spend, then get this one

Well, if you insist on one, then alright. 
Just try to understand that this is a very boring task having to look through 4-5 sites looking for prebuilts that I know won't be as good as quality as a custom made one. I'm just speaking for me personally, not saying for you to make a custom built one.
I may not reply for an hour or so as there are a few other topics that need my attention with custom builds.
Here's some links. If you see some you like, post them here.
