That' a pretty cool conversion. I've thought about doing that but those fridges are hard to find now.
That said, for that kind of conversion, where its just a lining, 900 is way too much. I wouldn't pay more than 300 for it, and then it would be just because its cool. I don't think that's spanish cedar inside either, Maybe parts of it is, but I've never seen spanish cedar with knots like that or a grain pattern like that. It looks to be somewhat bookmatched as well, meaning that its probably not solid, but rather veneer.
