If anyone is looking to convert their 5251 Beamspring into something a little more ergonomic as I did with mine, this top case is your ticket. The seller is accepting offers as well.
You did what now?
I think he just means a smaller, more manageable case—not changing the actual layout, as one might infer from such a statement.

Yeah, I know it's a bit odd, but I love this thing so much that I haven't used anything else for about the past 6 months. 
Wow, nice project! I don't think it's "odd" at all, just creative. And as long as you've preserved the original case somewhere (I can't imagine anyone just discarding it), what's to complain about? Seems to me, everyone's a winner. Of course, this is just me commenting on someone else's keeb-using habits, which is considered entertainment here in the suburbs.
