The Tempest Evo case is a very decent case, however compared to quality/feature freak (Lian Li) Lancool's series Dragonlord K62, and tool-less features/better quality on the HAF 922 (better cooling on the haf 922 once you invest in 3 additional fans), you get to see the it doesnt compare. HAF 922 has a total of 6 fans also once the additional ones are installed but boasts 2x 200mm, 1 120mm and 3 optional 140mm, or 120mm fans.
I find the Antec 900/1200 to be quite frankly overrated, I have seen Sony VAIO's have better built/more feature cases then the Antec 900/1200.
Like I mentioned HAF 922/Lancool K62 are gonna be your best options with a $100 budget)
Or GET A CORAIR 500r
