Once we get through the holidays, I'll revisit this and maybe look into building one myself. Way back when computers first started becoming popular, that's what I did all the time to get what I wanted. I spent more time researching hard drives, mother boards and memory, plus different types of cards and what not then I did doing anything else on the silly thing. It was more of a game with friends in finding the best deal for the best parts then anything else. Guess I did the same thing back in high school with my jeep. Now I hate modifying things or building stuff that I can just buy already done and ready to use. An AR sounds like a simple build, but if I do that, I'll spend a silly amount of hours researching every component of it, over thinking it, spending more for what I figure is the best, and in the end, probably not coming up with anything better then I could have bought off the shelf for a little more money.
