Hi there! I am a noobie to this whole "pick your own parts and build it yourself" concept, as my parents were never tech savvy and just bought factory-made computers whenever we would get one. However, the ironic thing is that I work as a student employee at my community college in their IT department. I know how to operate a computer well, I just have never really dealt with the hardware first-hand...so I am trying to better myself by doing this, as well as make a kick ass new gaming computer! I am posting these parts from my NewEgg list in hopes that I can get some feedback on my current decisions and maybe make some better choices/come out knowing it's alright to go through with this purchase! I had a little help from some of my buddies that I work with in the IT department that know hardware a lot better than I do... but I picked some of the things out, too, so I just want to make sure that all of these parts will work together to create a nice setup. Thanks!
P.S: The WiFi adapter is there because I live in the back woods where we cannot get an Ethernet cable hooked into our house, so I have to use wireless internet. So don't worry about that unless you have a better suggestion for one
