I think many dedicated NAS devices, are in fact Linux machines, using an
embedded Linux system.

Just a word of caution.
I had a simarly question: building one self, or buyding dedicated hw.
Looked through several specs of different boxes, and decided for an
ICY-box, that can hold two sata-disks, raid0/raid1/jbod, has an
GB-ethernet interface and capable of doing NFS. (which is actually an

However, the box is as slow as a proverbial civil-servant, although the
link is realy set to GB, it just might as well have been 100MB. And even
