I grabbed 2
2tb ssd's at Best Buy
I have this pc

one with the exact specs above.
I will do a fresh install onto a 2tb ssd.
I will download full blockchain to the ssd.
I will clone the ssd to the second ssd and to a 4gb western digital hdd.
Should cost me only for the ssd's as I have the pc and the hdd.
Good choice, HP OptiPlexes are pretty solid, although specs look a bit like an overkill to me. I guess it's a mini-itx case are you sure it can accomodate 2 ssd drives?
