I was wondering what the average usable lifespan of a decent case is. And by usable, I mean with modern hardware, new MB's, GPU's etc. I was planning on getting an Antec Sonata III for my build, but it looks like I might have some trouble cooling it so I was looking at some other options. The Antec P182 looks nice, but it's $60 more(with the same 500W PSU bundle on newegg+shipping). I dont want to get the Sonata and be wishing I got the P182, and find I need to get a new case for my next build. I'd feel justified in spending a little extra to get a nice case if I could reuse it for my next couple builds, especially since the more reusable parts I have the cheaper it'll be for me in the long run. How many years of use should I expect to get out of a case (the P182 in particular)? It'll be a few years before I upgrade again, and another few before I need another, will the case be obsolete by then? Thanks guys.
