We would need more info to help you. Intel or amd for instance. If you have a budget and just don't know where to start take a look at Logan's build videos in you price range and pick parts from them. Once you have a most items picked out then post them here and someone will look them over and offer advice from that point. Have fun with it because it is your build and needs to reflect you. Will check back to see what you come up with.
nice build. I also might change the case but this is a personal thing. If you like it then that is what matters. If you can get a few extra bucks I would get a high watt power supply. I try to never buy under 500w. If you are in the USA check Newegg.Tigerdirect and Ncxi.us for deal everyday till christmas. I have found some amazing deals in the past two weeks on parts.
