New to PC building, need help with case cooling

Rear and top should be exhausts, front and bottom should be intakes. As for the side, I'd say it depends on the type of Graphics card you have, you should just experiment a bit and see, fairly certain of the other 4 though.

Good luck

I have a EVGA geforce GTX 670 FTW

Go with an intake on the side then as that card exhausts heat out the back, it should also give you slightly positive air pressure helping to keep dust out.

Yes intake on side. The case I have has a 200mm intake on the side and I have the same graphics card and it hasn't even gotten close to hot yet.....

I have a 120mm Fan on the side of my Antec One.

My 560ti runs at 99% 24/7 and doesnt go above 80C, my fan is connected to the PSU with a 'quiet' connector for low speed.

Just go with the front and side as intakes. You would prefer the bottom to exhaust not bring in dust but a fan exhausting will just pull the air from the front fan. If you can use a filter then it could be an intake, but I doubt you will need it.
