Dell may be selling them, but seeing as they were just released (the same day as windows 7 retail), its doubtful that anybody has an OEM licensed machine shipped out in their hands yet. Let alone a person that has that machine is willing to share a copy out. Server OS's take a bit to get distributed out, it took over a year for 2008 Enterprise OEM to get leaked out from someone. Its not like retail, where 1000's of people go buy it in the store last week, OEM server machines are almost always built and shipped direct, and then somebody would have to share it after that. Even if somebody bought just the software from Dell, they'd get a retail box, not an OEM version which only comes with machines.
one year soo long why no one in the dell company is not so good to put the info here if someone want to buy a new DELL server, i m ready to offer him the price of the Windows 2008 R2 (169 euros!) .... unfortunatly i don't need a new server yet, just need the oem cd
