Don't fret too much on anti static discharge, just touch the case every now and then if you worry about it. If you're going to cable manage, do it as you install your parts because it's much easier to do that way. Double check that you have all your cables installed, I didn't have the SATA power from my PSU hooked up to my optical drive or my HDD, so I was flustered until I realized that. And try not to put too much stress on your cables, put them in cable management holes that allow them some freedom, as opposed to having them torqued in such a way that it could put stress on them and potentially the motherboard connector. Other than those, just have fun and be careful!
