i have 8gb memory and SSD for os and 8tb purple for cams 27 cam's
this is also on a 3rd gen cpu and i RDP into
i think you can get away with 8gb more is always nicer and it can be added at a later date
its a nice computer but i would not get it because the CPU has a T at the end and those are lower end cpus under power you want one without the T or S at the end
