Love the modularity, good way to keep components ticking away, as motherboards are always the hardest thing to find. Hopefully they can survive long enough to be relevant over the years, as of now I'd stick with a mister.
This could be good for the industrial world. There's many pieces of equipment out there that have a dos based terminal. We have a piece of equipment at my work that was made in West Germany.
Also, they should've made it a little bigger (micro-ATX) so that they could fit PCI and ISA slots for whatever weird retro hardware somebody might want to use.
