If you're ok w/ 3d printing them, there are a ton of models on all the free model sharing sites of various computers... most wouldn't need much work to accomodate a pi or something even if they weren't originally designed for that.

If you want something actually nicely injection molded like the PiDPs (which are well worth the price imho, if you're interested in them) I don't know that you're going to find a better deal. I suspect it's too niche a product to scale to being economical at lower prices.

3D-printed would be fine, except those are just statues. Aside from mounting points and IO holes for the Pi, models for an actual enclosure would need to be subtly adjusted so the holes for the keyboard and screen match up with available off the shelf components to add in.

There are quite a few options that already accommodate a pi, if you don't want to customize... see my other comment upthread for a couple, but that's just the ones I happened to have bookmarked, there are a _lot_ of results if you just search for pi cases on thingiverse or something.
