for what?is this a good set-up?
well since none of that is actually specifically demanding (i assume you mean video playback and image viewing rather than content creation), then it doesnt really matterthis is just for multi-tasking, i.e., videos, music, pictures, internet, email.
uh last time i checked, excelsior was a brand namenot name brand

HDD 101.actually i don't know the difference. is SATA better?
Uh well the X300 onboard will be more of a limitation than the CPUand all as long as your not really doing any gaming it should be a good lowend system
Not that any of it matters considering none of the stuff is CPU boundNo! No! No! Not a celeron! I would go with one of AMD's lower-level chips. You will notice a MUCH bigger performance increse.
They are, you're ok ... system is good .. realistically the only thing you'll want to look for is maybe better pricesThese aren't name brands???
