You should definitely build your own pc, you will gain some experience and it will be a much better system than the one in the store. About DELL, yes stay away from them, their tech support is horrible and the computers suck. My college recently bought all new pc's from dell and they tried to connect the whole campus into one big network. Now the whole thing isn't working and they have put all the pressure on one guy to fix it, poor mike. They can't fix it themselves or get outside help as it will violate the agreement. It is gradually coming along but it should never have been that messed up.
I went into the library and i kept on hearing the windows reboot chime, over and over and over again. I found out that they got some new software from dell as well and some idiot messed it up during install so now all the computers in the library are constantly rebooting.
