I'll be running ZFS, so I'm not really interested in buying a standalone device with its own RAID.
The NAS will be 'offsite' in an outside building (garage)
- No heating
- No cooling
- (I Will probably build a rat proof cage around it)
Requirements are:
- 6+ SATA disks, 3.5" form factor
- 1 x Gig-E network
- 1+ USB, bootable (to install software)
- Minimal graphics (will be a server, managed over network)
- WiFi
- Bluetooth
- CD/DVD (I'll install from USB)
- etc.
- OpenIndiana
- FreeBSD
- FreeNAS
- Mac OS X
- Reasonable CPU required
- 4GB+ memory desirable
- Mainboard
- Case
- PSU
- Supplier of same

Power consumption no greater than necessary (350W PSU is probably overkill)
I don't need disks, I already have a source for them.
Overall cost needs to be well under $1,000.
I'm note sure I'll go this route at the moment, which is why I'm asking for suggestions.
