Overclocking isn't really affected by your choice of case at all. Even if you're not going to overclock a roomy case with good air flow will ensure longevity of the components inside it.
Here's cases I recommend (AVOID Apevia, Raidmax, Xion, and similar brands) :
$50 - $75: Corsair 200R, Antec 300 Illusion, Cooler Master HAF 912
$75 - $100: Corsair 300R, Fractal Design Arc MIDI, NZXT Phantom 410, Cooler Master HAF 922
$100 - $125: Antec 1100, Corsair 500R, NZXT Phantom, Fractal Design Define R4, Antec P280
$125 - $150: Azza Hurrican 2000, NZXT Switch 810, Corsair Obsidian 550D, Cooler Master Storm Stryker, Silverstone RV02,
