You are wise to be concerned about particle board. Although its used fairly widely now in tank cabinets, the problems are real and waiting for you. If water somehow gets in to the particle part, it can swell up enough to unbalance the tank and cause it to crack and leak or to completely fail. For that reason I recommend at least putting an extra layer of thick-mil plastic between the tank and the cabinet top. It can be cut such that will not be noticeable but will still shed stray water drops over the side of the cabinet and hopefully out of harms way.
If you can find/afford stands that do not use particle board then that is a better option. The members here are great about pointing you towards things. If you look in your user controls, you should be able to find a place where you can update your "location" (as in city, state, country type designation) and this will greatly help people refine their advice to you.
