how much could i sell my mac mini for?

i want to buy a used macbook, so i'm selling my mac mini. along with the rather large flat screen monitor i have, mac keyboard, mac mouse and speakers. my mac is in almost perfect condition as well! fully updated.

after all this - do you think i would have enough? or should i sell all parts separately? or will i not have enough either way?

if anyone is interested by the way don't be shy;)
