Hi, I'm planning to build a cpu for my parents use for video streaming and some simple office work.
I have some old stuff but not sure which to use back. I would like to have some recommendation on this. My budget is as low as possible since it's for some simple work

Mobo: MA770T-UD3P
GC : -
RAM : -
CASING: Thermaltake Commander ms-i
