[Elecraft] KPA500 - stacking possibilites

[ai6ii]

Now that I have received confirmation of the delivery, I need finalize where
I am going to place my new KPA500. Given a very limited desk size (ony 34
inches wide), I wonder if the K3 can be stacked on top of the KPA500. I
undertand from earlier posts that there needs to be a minimum half inch
clearance on top of the KPA500 for the air intake grill. Has any FTer
stacked the two boxes to see if they work without generating too much heat?
