I just bought an x201 for the wife and I like it so much I would like to build my own for fun and as a spare which is okay to throw away. Since these computers are like lego systems, What would the best mobo/cpu be for battery life? I would use this only for basic tasks, which is why I was thinking that the old SL9600 or whatever would be fine. If the X41 is thinner/lighter I'd even consider going for that.
I would like to build:
X200s or light chassis with WXGA+ screen.
WWAN card
Webcam
SSD
The lightest battery
Fingerprint reader which works with Linux
Something fun in the express card slot
Trackpad and Trackpoint
Furthermore, does the X220 mobo fit in to the x201/x200s chassis? I believe it has USB 3 which is nice. I'm just looking to build a light bulletproof windows box that I can really abuse.
I know there is a x201s, but I hear it is rare, I'd like to not spend a lot of money so this could stay in the throwaway/loaner category.
