Vibration control inside a cabinet

This is kind of a tough question as it depends upon your cabinet and its' construction.
Though it may be considered heresy to some on this forum, I don't worry too much about it. Some of these tweeks can get a bit anal, as well as costly.
I mostly use Herbie's isolation for my equipment. Though I'm sure you can also use an isolation platform, as well. 
Another thread has been focused on Townshend Audio isolation products. The OP swears by them, and I have to admit, I am more than a bit interested in trying them.

I have some of my equipment on an Ikea Besta cabinet. I use the Herbie's isolation under them and have no problems.
