[Abhishek Thakor]

So i have a i3 12100 pc in spare and i am thinking of making it a NAS and Plex Server for home.
PC Spec:

• I3 12100
• 8GB 3200Mhz DDR4 (Single Channel)
• Gigabyte h610m
• Antec Atom 450 PSU
• PowerX M.2 240GB SSD

(Currently i don't have HDD but i will buy it for server)

I am thinking of using truenas and plex. Is it good idea or bad. Any suggestions or anything???
