Personally, I don't want to look at the insides of my computer while it's running. Using quality parts, I know everything is running properly. Plus, with mine as quiet as it is (want it quieter, but that's another thread) I can tell if something is up before I get the notice. It's also nice to not have to crank up the tunes to be able to hear them over the fan whine/noise.
I almost went with one of the Tt shark cases, but after looking at the pictures for a while, I knew I wouldn't have it for long. The lights that show through would eventually just piss me off and I'd have to modify the case to get rid of those (making it more expensive than it needed to be). Plus, the Lian-Li case has the sound dampening material installed on both side panels (full coverage), the top panel, and inside the rear fan shroud. Attention to detail in the Lian-Li is on par with what Foose does with his cars... :shocked:
