I make reptile vivariums for a living.
All you have to do to that unit is put a hardboard back on it ( £4-£5 ) , 3 vents at 40p each and get it listed on
www.rfuk.co.uk ( reptile forum ) in the classifieds section for about £75-£80, lol.
Actually, come to think of it........ I'm on my way now, lol.
