I don't see any glaring issues, but I'm unsure about the Cooler Master power supply. The CM power supply I had years ago, worked well enough. A 64GB SSD might be a little light, but is more than enough for just the OS and a game or two.
While you could go with any case that accepts an ATX motherboard, I'd look for one that has, at a minimum, 1x120mm rear exhaust and 1x120mm front intake cooling fan. The more the better, but also the noisier.
Edit: Oh - What's the usage for this build? If it's a gaming system, the drop down to a CoreI5 3570K processor. The gain (if any) in gaming from the CoreI73770k is not worth the additional cost.
I'd probably look at either a Corsair or Antec power supply. If you're doing more than just gaming, then the CoreI7 is the way to go, so long as it's within budget. By "glaring" issues, I mean there is nothing that is obviously incompatible. You should be good to go, out of the box.
Even if you are sticking with the i7 I would suggest not getting the Sabertooth, get the model down if anything. "Thermal Armor" is not as useful as it sounds, and to properly vent it you have to install 2 30mm fans on it, which I have heard can get quite loud. I do not think there are any features on it that you would need, at least over a model drop or two. I have the P8z77-V Pro, mostly the same features and it comes with a wireless module, I love it.
And yeah, I always say I do not trust a company that has to profess it's greatness in its name (ala coolerMASTER haha). Antec, Seasonic, Corsair, XFX are all good brands, just find the best deal you can on one with the appropriate wattage, Newegg has had lots of PSU's on sale (good ones too).
In summary, the SABERTOOTH Z77 is an excellent motherboard, but unless you really like the plastic cover, you should pick the P8Z77-V PRO, which is a little less expensive and has a few more features, or the P8Z77-V DELUXE, which costs a little more but offers a lot more.
