Keith,
All things being equal, I would use the laptop. You can disable the screen
and even close the lid, although I leave mine up about 30% for cooling.
There will come a time long after you install the OS that something will
happen and the computer won't boot. You then need to (1) find that old
monitor; (2) find the right cable; (3) find the right mouse; (3) pull out
the computer from whatever corner it has been relegated to since you
haven't touched it in, maybe years?; (4) hook up the monitor, mouse, etc.
and diagnose the problem. With the laptop, just fold up the screen, reboot,
hit f-something to get into safe boot, and diagnose the problem. The fun
part is when your partner donates that old monitor to Goodwill in an effort
to "clean up the clutter"....if ssh doesn't work, now you are shopping at
Goodwill for an old monitor.
This story is based on real life experiences. Only the names were changed
to protect the innocent.
