This same seller had most of those cabinets (all?) for sale a few months ago. They all sold - maybe some buyers backed out. I sent him several Emails, but never got a response.
I did buy one of his 19" Neotec monitors that he compares to a monitor on Happs website. His auction claims he has no way to test them, and that their condition is unknown. Since the monitors have a VGA connector and a power plug, and he obviously has a PC, I'm confused how he has no way to test them. In any case, the condition of the one I received was definately know to the person who put it in the box - it has a tag on it specifying it was broken and listed the symptoms.
