I saw this the other day. The SN draws a blank on Everymac, which does mean this isn't just a retail unit given to a dev. Someone else could also check the Leopard build number and firmware revision.

Having said that, the difference between this single penultimate model and the 1.5GHz iteration before it was just a processor speed bump, so this prototype is probably not that interesting internally.

The 1.67GHz launched with Panther and the Leopard Disk (Build 9821) doesn't follow the normal 5 character build number. It was used a long time by the dev if the Leopard disk is his.

Dual-link DVI on the optional 128MB GPU was also new for the 5,6; so were BT2.0 and the scrolling trackpad.

Looks like build 9B21 to me, which would make it newer than the 10.5.1 update (9B18). Several "early 2008" machines shipped with 10.5.1 9B2117; perhaps this one is based on 9B21.

this PB does look to be something apple internal :) but it looks be post PVT (with a retail firmware revision etc) so I doubt it has much different from a regular PB5,6 apart from the serial number and stickers
