tell you your speakers can put up for slae for more than 3
dollars. case you may try selling, all the optical drives, cables
(IDE/ SATA, floppy, power etc) sell at 1-2 dollars each also shiok,
psu, graphics card, no matter how old is worth a few dollars also.
motherboard please keep it with the acer installation cd you use
for formating and drivers install. you may want to write another cd
for your graphics card since the drivers for your graphics card is
in the formatting cd, unless you have it on a separate when you
bought the computer. the screen is world at least a hundrerd, or
maybe 40-50 depends if its lcd or what. lots of dollars more for
your computer, keyboard, mouse etc.
don't sell your hdd yet. unless youhave junk information nothing
personal, banking infor insight if not format it and use data
permanent wipe software clean them off. but such data wipe software
very expensive, permanent wipe can cost hnundreds or thousands.
similarly data recovery freeware can only restore 1st level data
and on smaller size data or files, it cost thouosands to get those
tht can recover data with multiple delete / overwirtten
passes.
i always write saving private ryan movie to my hdd all gb full
many times and delete again before before i sell. they have to
recovery until siao then finally get to see pr0n 
you can try FI market place but i think she got a bump 3x rule
before you have to post again. but such items sometimes have to
wait for a while before a keen buyers comes along so yeh ...
