Speaking of Xeon, you could probably put together a much cheaper workstation with an older Xeon over the eMag. I just don’t see myself picking this up, at its current price point.
Without knowing what the perf is like, it is really difficult to say. 32 cores @ 2.8-3.3 GHz sounds like quite a lot, I don't think getting 32 core Xeon would be anywhere near as cheap as this.
