I'm upgrading an old system with an Asus A7V and TB 800MHz. I bought a FOP32 cooler for the CPU but am planning on keeping the same case ($$$ shortage all the sudden). The case has a fan in front with just a vent in the back (plus PS fan and CPU fan). The only other major heat generators are a 5400rpm quantum drive and 50xCD-ROM but I eventually would like to upgrade to an IBM 75GXP (7200rpm). I have NO plans for OCing (I know, how boring is that?). Will I be ok with the case I have now (ie. will I Not be shortening the life on any components) or should I scrape up some extra $$$ and get me a new case.
