I'll definitely second the case and PSU choices here but I'd still stick with the Evo. IMO Zalman is kind of overrated for the fans they produce. You can't attach a second fan and the heat sinks tend to collect a lot of dust after long periods of time.
hey g-unit,may be you are right.how about hyper tx3?
Not a bad choice but I personally find fans that use rubber connectors and cheap metal clips instead of the plastic rails to be the biggest pain to install, mounting fans on the Hyper 212 is one of the easiest I've ever worked with. I'm not gonna say I'm a total CM fanboy but this is one of the best coolers I've ever used and I've used everything from single one-fan solutions like the Zalman 9500 to huge multi-heat sinks like the Thermalright Silver Arrow. I haven't tried a closed block like the H100 yet but I'm certainly open to it.
I have my Hyper 212 with two fans running and my CPU idles at 21'C and doesn't get above 30'C on full use.
