how inefficient are we talking? should I start from scratch? any recomendations?

hello all, first time poster here. i am looking to create what I think is best described as a home server, I want it to be able to run plex, blueiris for my home security cameras, home assistant, and possibly a few other things down the road, the more I research the more confused I get. do I go with a Pi, NUC, NAS? after over thinking it and looking around I found that like many of you I have a ton of old computer parts laying around but as i am new to the server world am unsure as to how viable these parts might be so an help would be much appreciated. The parts i have laying around: asus m5a99x evo mother board (not rev 2.0) fx 8350 chip hyper 212 evo cooler several 500 gb+ hdds several 120 and 140mm fans an embarrassing amount of thermal paste a rats nest of cables from probably 4 computers gtx 970 and soon a gtx 1080 once i upgrade the ram unfortunately i gave to a buddy but i am sure i can get some ddr3 for cheap I would like my home server and internet upgrade budget to 1000 max and this would include a modest ubiquity setup (would love some help picking parts for this as well). are these parts viable and if so what parts am i missing? if not then where should i start?
