I always get a stockpile of computer **** every year. Last year it was p3 machines and i put them together and sold 6 complete computers. This year i'm getting over run with a lot of p4 equipment and processors.
What i'd say is build them into computers and see if you need a file server, or any other kind of server for that matter. Or if you need a **** computer for extreme backup purposes (my dad's old pentium 120 lasted me until 2002 for a backup machine, it was a little slow, but good for everything except games).
But, you could always do what i do with hardware. Of course i do this for old hardware and malfunctioning hardware, and that is to chuck it in the forest. Most of the time i'll find a 20gb hard drive that'd be great for someones machine or my own backup, but chances are i find out quickly why the hard drive was free as my bios wont detect it. So, what i do as not to confuse somebody else with something tempting that wastes their time. I chucked that 20gb fried hard drive deep into the alaskan forests for no one to be fooled by it ever again. I also chuck obsolete hardware into the forest. And yes, have fun with this old **** of yours. Most of my other stuff went to the top of the local water tower and said hi to 100ft drop, and a nine iron as well.
EDIT: Slow down skippy on destroying the laptops. That thing has an xp sticker on it which means two things. It's powerful enough to run xp so you could probably sell that laptop for some good mulah with a legitimate copy of xp included in the price. Secondly, at least make sure to keep the xp cd, up here where i am, there not so easy to come by, and then you can at least sell xp for a good 75$. Damn, i wish i could get a free laptop.
