I have a microwave stand for my APO:

Fits perfect! $127 shipped on Amazon:

The BSOA cutting board also fits perfectly on top:

It's short enough not to cover the rear vents & has heat-proof riser feet underneath. $40 on Amazon:

It's really handy because the microwave cart doesn't have wings on either side, so there's no place to put larger, hot dishes to load & unload into the APO.
