Gentoo :
that is quite a build simple answer from what i see yes everything will work. i would say grab a sata hard drive, a 120 gb solid state drive isn't a lot of space. also i would say you don't need the mobo armor kit. lastly if you should use Ethernet instead of wifi if you can. if you just want the wifi adapter just to have it then thats fine.
Thankyou. I do have a 4Tb HDD with me that is completely empty! I will keep the armor kit, I don't mind spending the extra $50, It just looks awesome! I'm a little lost with the Internet part. We haven't had Broadband ever!! We still don't have it. So we are waiting for the NBN to come to our house (They say late feb. But I doubt that). Our home phone line is in a room that is about 30 metres from where I will setup my PC. I don't know if I can run a Ethernet from there. (correct me if I'm wrong, it does plug in there right?) Please help I'm a massive noob when it comes to Internet connections.
