Also, @bowei006 or @HybridCore or other PC-fi folks... I think it might be time for a PC case upgrade... I still have an Antec 900, but considering there's construction going on behind our house that's apparently bad enough to cause all the people in our neighborhood breathing trouble, I think I need something with dust filters... Would also like something without lots of LEDs, and is more minimalist. What get? The NZXT H440 looks beautiful but the lack of 5.25" bays is sad, and the build looks kind of cheap with the bright colored plastic. So now I'm debating between the Corsair 450D and the Fractal R4 w/ window... Looks like the 450D is cooler but the R4 is quieter. I'm not really sure how the 900 compares, but my Ivy bridge Xeon can idle at up to 45C, and the AMD 4870 Kalbee gave me seems to like idling at 79C in my current case, so I'm guessing I might need dat better airflow D:
I'd vote for the Fractal R4, mainly because I prefer it's looks.
A couple of degrees isn't going to hurt anything, so choose one you like!
