Don't get me wrong, I love the electric octopi that are springing up around my house, but there comes a time when you want to upgrade one of these "small projects" into something more permanent (in this case a XBMC solution amongst my coveted AV equipment) and give it a more polished look. Is this sacrilege to the church of Pi?
Cheers JoeDaStud for your links, I hadn't come across them before and they are near perfect for what I was looking for but as Plugwash states they're a tad bit chunkier than what's in the Short Crust case. That said, I might use them for another project.
I think after all this looking around and responses I might just get the Short Crust case. Despite it being a bit dear for what it is (a molded bit of plastic with an acrylic lid and the paradox of a smart power port locator that doesn't seem to exist... I suspect time travel) it does look quite nice, although I'd much prefer a choice of colours for the base at least. The way I see it, further down the line when I decide to upgrade or change the case I can rip the power port relocator out, laugh manically for half an hour and then use it on another project.
