I have one with a steel skeleton style case. Pm if interested. It isn't exactly what you are looking for but its miles cheaper
Finally created an account here just to reply to this. I'm planning a stainless steel skeleton b.87 build myself, so I have two quick questions if you'll oblige me (sorry to necro-hijack, btw).
1. Any info on the plate? Either where you got it from, or even better: dimensional/CAD info about the design? Sorry if it's a super-universal TKL layout and I could have found it myself; just trying to play it safe.
2. I haven't used any skeleton board before, and while I love the aesthetic, I'm slightly worried about noise/ping. How has your experience been with yours?
