Would it be possible to convert this cupboard into a grow box

Hey peeps, me and my brother had a duscussion about the price of weed and how expensive it is and now he wants me to grow for him but just enough for himself and me so we only want about 4 or 5 lowryder#2 plants. http://www.argos.co.uk/static/Product/partNumber/6091501/Trail/searchtext>CUPBOARD.htm I have done a lot of reading and studying about growing so i think i'll survive my first grow.

looks like decent cabinet, get your fans in it and mount some sort of lighting and go for it.
