old cheap laptop; linux; quiet

i am in the market for a used laptop in the under $500 range. it seems my only options are pentium3 or maybe a G3 ibook. thoughts? i need it to be totally quiet: i.e. fans don't spin under low load. it would be nice to have a centrino-M but i'm only going to be using this for websurfing, word processing and a few other things. no games; no photoshop or anything like that; just a basic laptop for running gentoo linux. any athlonxp-m's or other cpu's i could afford? ($500 is my top limit)

size is also important: i want it light even if that means a smaller screen. i know in my price range i'm not going to find anything "light" by today's standards.

i'm going to put a big hdd in for my music files, and upgrade ram to 512mb or 1gb if it is supported.

I'd recommend you look into an Armada M700 or if you have a bit more money ($350=$400) then check out the Evo N600c. Both are very small and light even by today's standards and the M700 I have has a very solid build.

check on ebay, i bought an hp zt1290 with a p4m @1.8ghz, cdrw/dvd, 64mb graphics, 512ram, 15" sxga+ lcd, 40gig hdd, and integrated WIFI for $460 shipped.
on the downside, the battery is crap, but those are $25-35 on ebay.

been very pleased so far.

i will be selling my insprion 1150 soon
mobile p4 , 1gig ram etc.... for 550$

Remember you cant buy or sell in outside of the classifieds.

Look into the IBM T20 series lappy's on Ebay.
