There'll be a couple curves in there, I just didn't want to (or need to) go to the effort of modelling them. As for the base size, that's the smallest it could be from the old design - I could probably make it a bit thinner (lower) now that it's a lot wider (everything doesn't have to be stacked on the motherboard anymore), but I do like the idea of being able to space things out and have lots of "breathing" room. The old setup was incredibly packed - here, check it out:

Note, those speakers at the bottom are new (since the old speakers were built-into the screen), they don't fit inside the case, and are the reason for the first rise above the control panel on the new design.
