WANTED DDR4 and DDR5 Computer Ram Memory

I am building AP computers for a few friends and need ram.  Please tell me what you have and what you would like ask for it.  The type and speed is nice to know but if you don't know what that is just photograph the label side of the ram and I can find that information.  I would also consider some M2 drives or SSD ram.  Video cards as well while we are at it.  

Thanks for looking.
