yeah, if you have some sheet metal skills and a Chinese factory, it's definitely an opportunity. Note, though, the vast majority of people buying in this space are the large corps who don't care as much about money as your brand, so, uh, good luck, I guess?
Honestly, I don't know enough about the costs involved with making chassis to know if there is much margin in the conventional server chassis business.
problem is that this is a company that sells to large corporations, so the markup is, ah, out of my price range.
