Hi again, just some other thing that came to my mind right now:
Don't leave your rx2660 in standby with mains connected over longer times, because its PSUs will get quite hot otherwise and most likely age faster than normal if not burn up over time. The DL380 G5 and DL385 G2 and G5 (at least mine, upgraded from a G2) all seem to have the same problem. [1] states it is a design flaw. [2] mentions that there are newer PSU revisions that might be OK in standby, so maybe you're lucky and have one of those in yours already.
