That is a great setup, you made me start making my own calculations, I own an old HP i5 8th gen with a Geforce GTX , a 512 Gb NVME and some 16 Gb ram, nothing spectacular, but with a pair of Seagates I can try to install trueNAS core and make some test with Plex... I'm quite lame with tech as I have no formation but I really enjoy tinkering xD - Well done!
