Dude......That is way too much money to fork out for a small drawer unit! I could draw you up a step by step DIY guide to make your own for way less than $500 all in! Check out what I started with and then turned it into :-

I could easily help you make a cool unit, If you begin with just buying the sized cupboard/drawers you are interested in getting, I can help you mod the setup - step by step.....Its what I am good at

You can barely hear my unit at all... So if I built one that was scaled down I am 99.9% sure I could get it to run silently

Also bare in mind running a 600 in that sized set of Drawers id over kill...Use a 400 Max, Lumatek do dimable ballast and ballasts with boost switches, I'd reccomend a 400w Digital ballast that can fire up both MH & HPS bulbs and has a switch to boost the lumens in flower (HPS ONLY)...
Chew it over man, I dont mind helping you at all

But paying that much is ridiculous. Let me know your thoughts - STELTHY
