A modern, power-efficient replacement motherboard for the Thinkpad X220/230

Would be absolutely fine if it were just a low-profile SBC that sat in the SATA compartment with some barebones connections out to the ports, keyboard, display, speakers, and battery. It can’t be that crazy of a product. There’s already million super-niche SBCs out there, literally the only hurdles would be interfacing with the proprietary keyboard (a solved problem) and the battery.

I’m jealous of my friend’s workstation that has an easily accessible filter in front of the case fans

I fancied the opportunity, but there were no other speakers of the language at my school.
