Help determine X-Serve specs

[rnizlek]

I recently acquired a few late-2006 X-Serve units via a surplus auction. They were brand new in box, and I am trying to determine the exact specs without opening up the boxes. Some of the specs are clear from the outside, but others are not. Here's an image from the outside of the box:

Here's what I've surmised from the above:

2x Intel Xenon 3.0 Ghz Dual Core Processors
4x512 GB ECC RAM (2 GB total)
2x80 GB 7200 RPM SATA Hard Drive
1x300 GB 15,000 RPM SAS Hard Drive
24x DVD-ROM/CD-RW Combo Drive
Mac OS X Server 10.4 Unlimited Clients

I am not sure what "MezGFX" is - it is obviously related to the graphics card, but I can't figure out exactly what graphics card is in the unit.

I've been cross-referencing the box against this page:

My questions are as follows:

• Does the above summary look right?
• Can I assume that the absence of notes about a configuration option like a dual power supply or fibre-channel card means the unit does not come with one? (I.E. Are the config summaries on the outside of the box typically all inclusive?)
• Any idea which of the graphics cards options this comes with?

I appreciate everyone's help in advance! Thanks!
