no, TDP is 125w on those 12-cores. They will also have EE versions of 95w, and those are first gen. 2nd revision will be better.
Yes there is a program rlubocki, it is called nLite. I use it all the time. I made an uber small version of WinXP that has a size on disk of only 192MB. But that is REALLY stripped down made for my gaming machine, it cant do a lot of the more advanced functions. A "fully functional" Windows XP that can do internet, email, office, games, and other "regular windows tasks" is an average of 260MB of size.
