xaw5126, you are mistaken.
"Multiple reports exist that the Mac mini was quietly upgraded in October 2005 to 64 MB VRAM, and either a 1.33 GHz (up from 1.25 GHz) or 1.5 GHz G4 (up from 1.42 GHz) processor, with 512 MB of PC3200 RAM. The 80 GB drive is currently a Seagate Momentus 5400.2 ST9808211A, which runs at 5400 RPM with an 8 MB cache.
At this point Apple have not revised the official specifications on their web site. This may be to avoid issues with discounting or discontinuing of old stock."

http://en.wikipedia.org/wiki/Mac_MiniDo note that for some who bought a new Mac Mini recently might have had received an older stock, which is nothing wrong per se, but if you are hoping to get the refreshed ones, order at a shop with the latest models OR try to check the serial no. of the unit (located somewhere on the Mac Mini packaging box), go to apple.com/support/ and enter that no. in the About Your Support Coverage. Note if it says Mac Mini (late 2005), which if it is, then Bob's your uncle!
But to be absolutely sure, boot it up, and check the specs out at the About Mac. Then plonk your cash.
