I don't do Intel builds, so take this with a grain of salt.
-First step would be to google "z68 roundup".
-RAM something like
this? You can get a lower CL if you feel like spending more.
-Air cooling? I use Noctua's range, but I'm sure there are better options
-Case is personal, Anandtech & tomshardware do reviews
-3d monitor options are limited (& pricey) where I shop. You could go
this, but for that price range I'd just get
one of these
Where do you shop? Umart is one of the best by price, but if you want specific stuff you might have to look around.
Edit: Noticed a couple of cheaper monitors. I have nfi how much the glasses cost tho. Refuse to research smelly gimmick properly...
Edit2: Upon reflection, I can't recommend any monitor between generic ~$200 x1080 led\lcd and $500+ x1200 ips. Unless you want qaulity 120Hz.
