This computer will mostly be used for programming, local server testing, virtualizing Linux distros and (non-hardcore) gaming. Occasionally it will be used for video editing / 3D modeling.
Maybe I should have considered better cooling, as ambient temps are around 37ºC (99ºF) during summer, and I've seen CPU idling at 38ºC sometimes.
I live in Spain. As you can see and as you might have expected, computer parts and in general technology (and more in general, everything) is ridiculously overpriced. I ended up buying most parts at a german e-commerce website that seemed to have the lowest prices (that I had access to) here in Europe. The parts that are marked as "already purchased" are the ones I used with my old PC.
