I don't see any port for the Ethernet cable that runs out of the front of the S3. (s3's arn't wireless) Also if this is a Urack server encloser where is the psu going. I like the idea but this just seems to be as effective as putting 3 S3's next to each other with ductape except room for Ethernet cable. Don't mean to sound harsh just don't see the point of current design. Would be interested in a 4 unit S3 Urack design with room for two of those dell 750w psu with breakout boards. Then we would be cooking with peanut oil.
