Cable management in that particular case I do not know, but it cant be much different to other case designs. Heres a good tutorial for cable management, its in another Corsair case so it cant be that different.http://www.youtube.com/watch?v=ERhxmzQR6xA
Generally the idea is to tuck the cables somewhere so that they dont interfere with case airflow, and aesthetics if you can see into the case.
Good budget cooler is the Coolermaster Hyper 212 EVO. Not sure how much it will let you overclock for an FX-8150 but its gets you medium overclocks on the Intel side.
