Different iMac stand to lower iMac

I'm trying to set up my new late 2012 27" iMac and it is too high on my desk. My neck is really beginning to bother me. I see that an adapter kit is available (http://store.apple.com/us/product/MD179ZM/A/vesa-mount-adapter-kit-for-imac-andl ed-cinemaor-applethunderbolt-display)

but it says: "Note: Not compatible with iMac (late 2012). Wall mount or articulating arm not included."

It's currently about 2.5 inches from the top of the desk. Lowering it 2 inches would really help. Not sure if it'd be enough but would be the best I could do to still allow air flow from the bottom.

I never would have thought that it would be too tall.
