im thinking of buying this pc.

then modify it. adding a graphics card ,a second hdd , and a wifi adapter.
the reason i chose it because it has windows7, not interested in win10. so my choices are limited.

i have several questions:

1- is it suitable for a home pc? seems to be marketed towards workstation customers, which i don't know if it will function perfectly for my needs (daily internet & videos, and occasional gaming).

2- the psu is only 240w, so what graphics card should i install? must have hdmi.
