Hello there everyone I am here mostly to get feedback for the build that I have picked out. Primary purpose for this box is tinkering and learning various Linux distros. I am using spare parts along with new to help keep the price low. Also this box is going to be hooked up via HDMI and will be using wireless keyboard/mouse. Largest IF is what graphics I should use.
Whatever you do get an nVIDIA card, MUCH better driver support in linux trust me I have first hand experience that ATI/AMD cards have horrible support for linux in general. Also get at least 2GB of RAM.
Yes, a 520 is good for basic stuff and of course has superior linux support. You might also want to look around for some other nVIDIA cards if you need more power because the 520 is about as powerful as the 210.
