I would use this tower if you can , but then again, it is up to you. It has 5 case fans, and a 500Watt PSU that is Ultra Quiet! Plus, it looks snazzy, and has track systems for the drives, so you DO NOT have to screw them in, and has a fan controller on the front for system noise reduction. The viper case is nice, but I think it has a few downfalls. One, it is kinda flimsy, two it has the ugly viper head on the side, and three, I have heard from my friend Matthias, that the PSU on it tends to be load, a makes a crackly sound for like 2 mins after you turn it on. He replaced his PSU with an Antec PSU because of it. Check this out, then tell me what you decide on.
or check this bad ass case out. It is a bit pricey, and DOESN'T come with a PSU, but it is one of the best made cases around, and looks really cooL!
or this one, same things really, except cooler front panel looks.
Your link was broken, so I found the Viper Case on newegg, maybe it is cheaper then what you found.
