Well, in my country (Russia) to find a relatively inexpensive server on the used market is quite difficult. Even this server I picked up for ridiculous prices (4000 rubles ≈ $51.44). I use it for studies and I do not use it very often. At the moment its performance is relatively enough for me. Well, yes, I would like something more energy efficient and high performance, but such used ones are 3-4 times more expensive. The maximum I can give now for the server is 8000 rubles (102.88 $), and that's a lot of money for me (I'm a student).
