I actually know (but am not affiliated with) the seller through personal experience. I think you guys are being more than a little unfair in persecuting him as a fraud.
Perhaps, it is possible that DVD owned this machine, and that the case is missing - the case hasn't been on my 4000t since I got it as I am constantly hooking up different drives and plugging/unplugging cards.
It is most likely (if you know about the toaster flyer) that the case was left off to allow the connection of the scsi array given that the case does not appear to have any external connections for such. Without an array of sorts, the flyer can't work - maybe that is why the case is off?
You should not be so quick to condemn without reason.
