Questions about Intel Arches Canyon

I have two Kingston RAM bars from an old Sony Vaoi laptop with the following spec: 2GB 2Rx8 PC3-10600s-9-10-F2. Unfortunately, I can't do much with these numbers, so the question: does it fit the NUC? PS does an SSD 2.5 inch fit? or does it need one with M.2 format? Thanks!

The description reads the following: "Linux Version Linux , Linux Mint , Ubuntu , Fedora , OpenSUSE". In Ubuntu https://www.ubuntu.com/download/iot/intel-nuc-desktop However, under point 1 only 7n Gen. NUC's are listed: Where is e.g. the Ubuntu ISO Imag for this NUC?

does this ram work in this: • PC3-12800 • Unbuffered • Nonparity • 204-pin • 1600MHz DDR3 SDRAM thanks

Does anyone know if the part also supports HDR? I can't really figure it out from the data sheets.
