Ok, I have given the fan thing alot of thought over the past day. I definatly want green case fans. I'm using blue right now, so I want something different more than anything. And I think a black case with green fans would look sick.
These caught my eye:
Newegg.com - APEVIA CF12SL-UGN 120mm Green LED Case Fan - Retail
They only have an average of four eggs, but I looked at the exact other fans in different colors, and they all got five eggs. Plus, I saw one review where the user put these in his 830 evolution, and had nothing but good things to say. I'm not very picky about noise. I run my Sapphire x1950PRO fan at 100% when I game, and it sounds like a hair dryer. I've slept with it on overnight before, and it doesn't bother me a bit. So as long as the case fans aren't absurdly loud (which I doubt they will be), I'm cool with it.
