dresser grow.. first on my own

i've grown with other people but not by myself yet. below is a cabinet/dresser that i have and want to turn into a grow cab.. im gonna use mostly fluorescents but i do have a 70 watt hps (yeah hate on it..)

and ideas for reflecting, light placement..anything?
i dont have a ruler on me at the moment and ill check to make sure but it's around a 4'+ high x 20" deep x 3' wide

again that's just an eyeball

come on.. anyone?
a buddy is hooking me up with some hydro equipment so i think that's the route i'm taking

also i believe i'm going to order a t5 4 tube 2' fluorescent fixture for right above...

i'll have better pictures later on tonight

do like this one is setup just adjust some things if you have to so it will wrk in your situation/dresser
