just a thought: have you considered an AMD APU?
I didn't see you mention which or what types of games you're aiming for. An APU would be "enough" for quite a lot of things... but i certainly wouldn't build an APU box for bf4.
That said; if you aren't aiming at anything highly resource intensive (like bf4), a little APU box might be a perfect mid-grade solution, while awaiting the shiny new whizbangs on the horizon, mentioned by ivan (and a good point that was). I wouldn't want to invest in a new rig with all that new tech on the horizon.
I also second the seasonic recommendations; they're almost always solid and reliable.
Check this out (PSU manufacturers list). A lot of other PSU are based on either Delta or Seasonic designs, and many are actually made by either, rebranded, or use all the same parts but are assembled elsewhere.
As for cases... until i read in this thread that corsair has been using proprietary configuration tactics (reduce/eliminate compatibility with other brands' accessories!?), i would have given them my vote for best mass produced cases. I like their designs and looks (specifically the carbide 300R and the obsidian 900D), but i always prefer modular/moddability over being locked into any certain company's parts. Shame. I have a hard time finding cases i actually like, that aren't huge or expensive (or look like a plastic robot), which lead me to investigate what would be required to build my own... which probably won't happen anytime soon, if ever. I simply cannot seem to find a reasonable replacement/upgrade for my Lian-Li PC60b (aluminum, "plain," slide-out mobo tray, mid tower). Everything cheap is worse, everything better is too much.
