My last build was an ultra tower. This time I went in the other direction, cramming a decently powered build into the Phenom chassis. I did a bit of research and read through some reviews ahead of time - this helped the assembly process go as smoothly as possible.
While you may want to set aside a bit more time than you're accustomed to, it's really a great case to work with. Space is tight but a bit of patience gets things sorted away quite easily - I was pretty happy with how this turned out.
There are two fans up top blowing down (in), the fan adjacent to the CPU cooler is blowing out, and the bottom 200mm is blowing down/out. The PSU is pulling it's own air in from the front. I may flip the 200mm around and have it blow up for a positive pressure setup, but temps and noise levels are well within acceptable bounds as is.
Temps have been pretty decent: with the case fans on pretty low settings, the R9 290 is staying just below 75C under load, whilst the CPU hasn't broken 55C. I'm not overclocking, and these temperature levels aren't fantastic, but for a small case lacking tons of airflow I am satisfied.
