No, probably not. Also, a 15K RPM drive still isn't very fast (compared to RAM)

Apart from wondering how you're getting the motherboard to get past
POST without RAM, I'm wondering how you'd get the bootloader and
kernel to load in a RAM-less system. You could probably do it for a
system with a minimal amount of RAM and let (most) everything run in
swap, but that's just going to be ridiculously slow.

Any particular reason you're looking into doing this?

Kind regards,
