I have owned this rack case for about 5 years now. I bought it to house a 100 Watt valve power amp, which is extremely heavy, so the rack case needs to be very well-built and stable.
The case is still OK after 5 years of use, which I think is very good. The case is constructed of Plywood, with metal corner protectors and edges. It is very well-built, and has heavy-duty door catches. It has the standard slots with holes for rack-mounting. The power amp I am using needs to be supported at the back as well as at the front, so I had to make special brackets for this. This is the situation with most/all rack cases, as the slots and holes at the back are the same as those at the front, but power amps don't have the rack ears at the back, so don't fit.
The case has big rubber feet for stability when it is on a table or stage and the case doors are open.
I would recommend this rack case and would buy another.
