Then you can pick out RAM (2GB; cheap) & 2 HDDs (1TB; RAID 0) and maybe an optical drive for installing software or burning disks. Some mini-ITX cases can house a dvd drive + 2 HDDs (one may be vertically positioned).
PSUs don't need to be big. 100W-200W is ok for nettops.
OS can be XP or Linux or NAS. The first are useful if you need Internet once in a while. NAS will only do NAS, no other apps allowed.
