So you have heard some of us talking about how we have file servers at our homes to provide our network users files and other things.... Well if you dont want to spend the money or find that stuff to complicated you can now opt to pick up Linksys' Network Storage Link for USB hard drives... What this does is take a USB hard drive and plug it into a free standing hub with then plugs into a  router or switch... Not bad for only $99 plus the cost of a hard drive... Ofcouse you could buy a USB adaptor for a hard drive you have and then it would be even cheaper... take a look... http://www.linksys.com/products/product.asp?grid=35&scid=43&prid=640
