As this is a range of bespoke machines, there's no set price, and it's a little difficult to write a definitive spec list. There are a range of options, and some other interesting tidbits: for instance, two units can be fitted side-by-side in a 1U rackmount enclosure - it's as wide as a single magazine page and just slightly taller than my USB mouse, according to an ad in Qercus. It's also the first machine to use Adjust as its default OS, or an as-yet-unnamed "RISC OS OEM". Linux is an option too. The orange colour is RAL2004, and the rugged steel case should withstand driving over it in your car, although I'm not sure who's going to be the first to test that!

An example given is a silent machine with no moving parts (i.e. flash storage). Put this together with the rugged case and a low voltage option that can be powered by batteries (charged by solar panels?) and you have a go-anywhere machine. Now if only it came in a laptop option...
Example builds will be shown at the Wakefield show, and a dedicated website is available here.
