This is a Cisco Web Security Appliance S680, which according to Cisco specs has dual E5-2680. I believe these are just plain old x86 servers with branding on the outside and their appliance OS installed. Uses 2.5" storage form factor, and usually Cisco stuff uses LSI stuff for storage. I don't know what kind of backplane it has, and it might be a HW RAID card. But for $460, it makes for a very cheap dual E5-2680 server, it should come with RAM and HDDs and is ready to turn on. Comes with rails and console dongle too.
