Well thanks to Mr B and friends, I built my first pc. I knew ED was coming and wanted to be prepared
The shop bought Packard Bell machine I had for 2 years was not for gaming. It was a micro case with one fan

. Kept over heating (non airconditioned Spain here)
Wanted to get best bang for buck so took the plunge. Recycled the i7, hd, and cd drive. Corsair Vengance case (with window, I want to see my creation

), GTX 660, 120gb ssd, after market cooler, loads of fans. Nothing amazing, but for me it´s great. To top it off got 2 19" square monitors for free that sit quite well either side of a 22" wide screen. Works a treat.
The Mrs then got PB for me for xmas. Hid the paper work in the bottom of a box of socks she bought me as a gift. Funny girl.
Managed to get a T-flight HOTAS and bits for head tracking out of her for valentines day too.
The worst thing about building my own PC is, now I want to do another. Really enjoyed the experience, researching parts etc. Think I´ve got to get a few years out the one I´ve got though.
Wouldn´t say they forced me as such, but certainly inspired.
