Canadian Home Workshop magazine had detailed plans for a nice cabinet in
their September 2002 issue. Mission style in quartersawn oak, using a cooling
unit from Vintage Keepers. Call their subscriptions department; they may
still have some back issues.

They used signboard (plywood with vinyl coating) to make the inner part of
the cabinet.

I built one; it looks and works great.
