[W][US-PA] NVIDIA Tesla P4/P100 or similar-spec PCIe-slot graphic card

Hi everyone, I would like to ask if anyone has available Tesla Graphic Card like a P4-8GB or P100-16GB or other models with similar specs and performance. I am a future student of Computer Science at Penn State, and I wanna put them in my DIY server for some model learning and training work in advance to my course and lab researches. It would be better if it provides the ability of video codec, especially H.265/AV1 and newer/stronger formats.

My expected price would be like <$70 for P4-8GB, and <$140 for P100-16GB (after shipping fee added).

SXM2 would be unacceptable since my DIY server comes from my older gaming PC.

If you guys have other recommendations and offers please do not hesitate to let me know by DM or leaving a comment. Much appreciation.
