Looks like youve got everything, tho personally the nano itx is a bit of a bottleneck when it comes to video/visu playback, but meh, each to their own, still a great board
However, im at the same kind of level as you, in the sence of ive just finished working out what i want. but not fully how im going to go about installing it. so ultimatly unless youve already worked out power, fabrication etc, i'd nock that 70% down to about 30.
anyway, best bit of advice i can give you atm is, the parts look great, just take it slow and know what your going to have to tackle next.
all the best
