11.12.02 Most of us have at least one or two older cases and older system components. Seems they could be used to construct a Network-Attached Storage (NAS) . ... I have W7 home and sata2 hd and transferring files between hd can be at 20 (usual) upto a rare 140MBps; at this point i look fwd to getting an uncommon 60MBps. So, looking into a separate system and wanting to avoid $300- $3000 for just moving backups and bulk to storage, seems the answer is converting one of my old cases into a NAS. ... Are there special small form factor motherboards and software needed to construct such, or can one just use a previous OS (Wxp) and the older system for basic archival storage? Those $300 - $3000 NAS really do not seem to transfer data much over 20MB/s. Ideally i would like a mobo that could process three to six sata3 (6GB/s) hd @ 50 - 80MBps with ethernet connection to my existing w7 desktop; the older mobo barely could accept sata1 much less modern sata3, hence why looking for a NAS type mobo instead of an ordinary modern mobo. ... Any feedback is appreciated. (tough to get this forum to respect paragraphs!)
