Yea the a-10 is on the us chopping block. Could be their next step.

the cold is helpful but moving the heat, but is the hard thing getting it away from the space craft. Since there is no atmosphere to take away your heat it just kinda sits there. If it is getting the suns rays it can be even more difficult. so basically it is quite hard.

for ease of use i would not use a pci coral. usb just is easier. passing the usb through to a dock or vm is easier. i use unraid and it was extra work to get the pcie vs usb coral setup. I have a nuc with a bunch of ssds for this kinda thing too.

Three versions that I know of have it but you’re right it’s not common. https://www.intel.com/content/www/us/en/support/articles/000091705/intel-nuc.html
