I got this tesla K20 at an auction for the price of a kebab (W/L btw). No one knows if it works, it worked 5 years ago and was just lying around since then according to the seller.

I cant just test it normally because it has no video outputs and the only motherboard i have only has a single x16 slot and my cpu has no integrated graphics…

Any idea on how to test it without spending money on additional stuff?
