You want a solid, stable rack to capably support your gear. Each piece of kit should have a proper footer underneath it to manage/eliminate vibrations getting to your gear.
One of the most effective and reasonably priced footers can be obtained from Herbie's Audio Lab. I use their "Tenderfeet" under each piece of my system to great effect.
Another advantage to your system is decoupling your speakers/subwoofers from the floor. Allowing the vibrational energy of the speakers to dissipate across the floor rather than be vibrated into your rack will do wonders. BTW... Herbie's has decouplers too.
