Thanks a bunch in advance!

Get the first build, ditch the RVZ01 and try to find out when does the FTZ01 becomes available, it's the same case, but with a more professional look, no plastic, all aluminium; as well as a better back panel design. Add a filter for the PSU for it.

I really don't see how will the AiO really help? Get a Prolimatech Samuel 17, it's basically the best low profile cooler on the market, it doesn't come with a fan, get a Noctua NF-F12 (PWM) for it.

For the PSU, get the new SFX-extended one, it will fit the case, but has a larger fan instead of the 80mm one that is noisy for some people.
