I started a Facebook group called MXPC
https://www.facebook.com/groups/myextremepc/?fref=nf
The page has been up for just over a month I think and we've already hit 950+ member mark. The page has been a constant slaughter of contests. I have already given out over 50 FREE game coupons, a GTX 560, two GTX 560Ti's, a GTX 550Ti, a Radeon 6670, a computer case, multiple power supplies, SSD's, memory and hard drives.
Right Now I'm giving away a complete Mid range Gaming system to one lucky winner (to be drawn at the end of Dec)
Soon we'll hit the 1000 member mark and I will give away an EVGA GTX 770. Please come make my new home your home too. We're enthusiasts interested in Gaming, modding and anything PC related.
