Isolating digital components?


So....does it makes sense to isolate the Mac Mini, DAC and transport? Who's doing it and how exactly? Benefits?

I currently have the Mac Mini sitting on a 1/8" thick Latex pad. I put the Apple CD burner next to it. The Rega DAC is sitting on 1/2" thick of Phthalates/Latex.

Any better ideas?
