Norco DS-520 home NAS is probably more server than you need
We're not certain what kind of home user needs a NAS solution this hardcore, but that's what Norco's targeting with the DS-520, a hot-swappable five-bay SATA II NAS that's actually a Celeron-M computer running your choice of Windows Home Server, XP, Linux, or "any other x86-based OS." The unit hits your network through the two Gigabit Ethernet ports, and you can configure the drives as RAID 0, 1, 5, 6 or JBOD arrays, and once you've maxed that out, the three eSATA ports and four USB 2.0 ports let you expand the system even farther. Those of you ready to max out your home networks are looking at dropping around $620 when this bad boy ships later this year.
