Have an HP mini 9 here with 7 Starter (not eligible for free update but still cheaper than scratch) which apart from the onboard network being b0rk3d and no SD slot works for the most part.
For all of £11 + a cheap 240GB SSD from a friend who upgraded to a 500GB this dinosaur may yet survive to scratch un the dirt another day, seems a shame to waste a new battery and other bits.
Protip: copy OS from recovery on slightly more recent HP netbook with identical chipset and do one crucial update (GW10) then install 10.
This assumes you have the old drive to recover from and know how to image, resize etc.
Also worth checking is that the BIOS is indeed the latest version, my old board has a socket so it might also get upgraded to a 25Q128 as these old Eon chips are very prone to failure after such a long time.
