Yeah, I've seen that, I was kind of hoping to take advantage of the
fact
that the Cubid cases come with a 12v ATX PSU (i.e. they use a laptop
style
adapter to do the 240Vac->12Vdc, then there's a small board on the
inside
that does all the rest)

Also, Sproggy's PSU has a max of 1.5A @ 12V, where as I think the Cubid
needs 2A to boot :-/
