I do that every two years. But I still end up buying a new motherboard or something. I got the itch again, I doubled my RAM and added a new m2 HD. Two years ago I repurposed three PC's into 2 high end gamers with about 6 or 800 in parts added. Ia wanna do it again!
I can't afford it this year though, I am mostly limited by an old monitor, and need that first I suppose.
