Thanks fawkes, Steve. Almost ready to try turn it on now. Just another question, my cable management is ... okay, nothing really blocking airflow but the cables are quite bunched and clusterforgeted together both next to the CPU, and some stowed in a space below the hard drive (got those cables where there are "stems" of cables coming off of multiple thicker cables).
Is it okay to have tightly packed clumps of thick power cables together?
