Nice. The thumbnail image reminded me of an Open Pandora, which similarly looked like a chunky DS and ran Linux (it was mostly intended for playing emulated games). The Pandora was never that repairable though, in the sense that it was mostly a system on a chip.
Before I even looked, I thought that I bet this device is more expensive than I'd assume - the crowdfunding site is listing prices roughly between $1000 and $1500.
