I think my cabinet's legs are slightly different than the models shown in the photos, but I'm sure the chassis is the same as the RA-112A.
It occurred to me that given this cabinet's extra width, a 16:9 flatscreen could go inside, (better the the dumpster it was headed for) but I'd rather the cabinet be used for its intended purpose.
If anyone wanted to spread word around to any other forums, it would be appreciated.
