you will have to search for it, I remember reading a thread a while back (few months at least..maybe december of last year) about someone that modded there Alpha Pal so it would fit on the AK31, there is a capacitor in the way, and the Alpha may also contact the NorthBridge fan...he had pictures in the post to show the mods...I believe he used a drill or a CNC to cut away the lower part of one corner to clear the capacitor.
