After more than five years, I finally upgraded my Desktop. It was way past time! I really wanted to build a small, compact computer this time, but I have a raid 5 array that I wanted to migrate from my older machine. This means that any case I choose must support a minimum of three 3.5 inch drives and one 2.5 inch drive (for the OS SSD). I settled on the Node 304, even though it is not the smallest or cheapest ITX case. It is just the most affordable, best designed case that works for my needs. I purchased a 1440p monitor earlier this year, in anticipation of this build (I was given an offer I couldn't refuse) so I needed a computer that could run games at that resolution. While I didn't set myself a strict budget, saving on cost when possible was a priority, so I ended up purchasing an R9 280 which seemed like the minimum spec for powering my display. You already know I'm re-using some hard drives from a previous build, but I'm also re-using a power supply, monitor, keyboard/mouse, and some other peripherals. I've listed them and the price I paid for them below.
Edit: You can see that the power supply pictured has way too many cables to fit in the case properly! I broke down and purchased a Silverstone ST50F-P (http://pcpartpicker.com/part/silverstone-power-supply-st50fp) to replace it. This power supply fits far better into this case.
Edit: updated the build photos with the new power supply. There is still some cable mess, but at least the GPU can breathe, and air can come in through the front of the case now.
