Not sure what you are asking here....???
It took me two days to install my system. The extra day because I was drinking the first night.
Up until I got wireless Internet, I had to bring the system into the house to do upgrades (2001). Since then it hasn't left the car for more than a few days.
I think people usually plan out their systems ahead of time and/or order everything all at once. Unless they're doing some really custom work, I think most people put their systems in pretty fast.
Did you get linux setup yet? Why don't you just use that laptop you were given?
