old engel fridge on it's side???

I have an old Engel (sawafuji motor?) front opening fridge. I find the front opening design is a bit restrictive - can't really fill it up, and things slide about a bit...

Anyway, question is - if I fashioned some legs to suit the back of it (to allow some ventilation, maybe 4" high or more?) could it be used as a chest type fridge? I've read that compressor type fridges can cope with running off level, but is 90deg asking too much?

Cheers,
Charlie
