This ^^ Brave and repworthy
An interesting build, with potential to be great, because of the limits of the case.
One thing to note: Make sure you have airflow over your mosfet/nb/sb heatsink now you have that chunk 120mm rad in the way. You don't want those to be melting while you cpu chills out. NB and SB usually have temp sensors you can watch, but your power circuits are usually not monitored for heat, and are just as vital for your machine.
