How to build a PC? in Everything Geek Q&A Posted March 21, 2012 · Report reply I built my own several years ago from Tiger Direct. They had a sale on a group of parts that all worked together & it all went well & operated OK with the win XP I bought. I replaced it last year because I wanted to have Win-7 Op Sys. I bought a new discounted HP from Walmart for $400. I am very happy with both decisions. I am not a gamer so I didn’t need the biggest & best for my casual usage. Newegg has some good deals too. It was very easy to build just follow the instructions faithfully!!
