I think buying a premodded case is for ppl who are lazy to make their own or dont know the knowledge, but still want it to look good and show it off. There are ppl around who dont even know what each part does inside the computer, how they connect to eachother and all that, but they already have like 3 cold cathodes in the box to show it off. They will never mod anything because they dont know how and dont have the resources to do it, therefore they will always look for premodded stuff. Personally I dont like the look of alienwares and voodoos because I know that I can personalize my case the way I want and I dont have too look at someone else's style when I can look at mine. However when I shop for a case, I look at its potential to be modded and its layout.
