I know that there are feet are on the right side of the case, but if I were to place the KPA500 on its side, i think I would create a stand so that it can sit on the left side. Why?
The big weight (power toroid) is on the left side, while the heat generators (the PA transistors) are on the right. The center of gravity would be lower, cables would be down low (especially the power cable), and the fans up high.
The only heat generators on the left side are the power regulators (for +5 and +12V). They don’t generate nearly as much heat as the PA. The down side? The carry handle is on the left. That’s why a short cradle would be needed to lift the case above the handle extension.

Just opinion, not an official recommendation. Mine sits nicely on its bottom feet with the KAT500 on top. That allows me to cable the two very nicely using custom cables.

First, be sure to leave the 4 inches of free air clearance next to the top (top as in standard orientation), and don't set it so that the LEDs are on the floor.  The orientation isn't odd, really.  If it is resting on its right side the power switch will be on the rear, but very near the top edge.  That's how mine will be, when it arrives this week --- I hope..
