Personal comments:
I was really impressed w/ this NAS but since it is running Windows 2000 it did get the MSblaster worm from a networked laptop. It does come with a Symantec NOD antivirus but that had to be activiated over the internet and was only good for 3 months. These pictures were taken from home when I had to clean the blaster worm out and install the company standard antivirus software instead. Also updated windows from home. It is back in the data closet operating fine till another Windows security hole is found :-(

This did come with a SCSI card eventhough we didn't order one. It did take a long time to get shipped and Dell is known for throwing extras in when they delay a shipment since prices fall fast. Good quality exemplified by the Hitachi Deskstar hard-drives (formerly IBM) and the Samsung ECC RAM. I have a bias against Western Digital and Seagate. Dare I throw Fijitsu's name into the mix because of thier HD fiasco in Europe and Asia?

Windows clients use it fine. Macintoshes are okay with appletalk. Why is the default for Mac OS 10.2.6 CIFS/SMB when connecting to it though? I thought they wanted people to switch. I would think Mac OS 10 would try to use Unix (NFS) or Appletalk (AFP) as its default network type. It will be primarily be used to back up PC clients running a batch file to copy all files from the desktop and My Documents folder at shutdown.

Front hard-drive section was real cool to the touch but the CPU and power supply areas were warm and hot to the touch on the case. At least the hard-drives are kept cool which is the most important thing. It has great potential because of its price. Way cheaper than IBM, Gateway, Apple Xserve, generic, etc... because of the great Dell warranty/service. I'm sure it can be a good VPN (Virtual Private Networking) solution also. Speed was fine since it is just being used for storage on a 100Mbps network. Best part is no server/client licenses to pay. Number of connected clients only limted by the type of network OS they are using. It does come with licenses for each network operating system on stickers on the case though. If you are looking for cheap storage over a network get a NAS. Especially helpful as backup or inexpensive unix storage. I just hope that they will eventually port Windows 2003 server to network appliances like this so that I can do everything in command line. Don't forget to put this behind a comprehensive firewall!!!
