Have to agree here :) With AM2 the Athlon 64 EE SFF (35W)* is a nice
option - or the new BE 2350 with 45W.
Other options are Socket 754 with the Turions and sempron mobile with
35W resp. 25W depending on the model (This i have running).
* EE SFF is imortant as the EE has 65W TDP.
* the availability of all options except the BE is not that good i guess
- don't think you will get it at the store around the corner.
* VIA CPUs are not midrange but low range processing power
* for processing power per watt the two athlons will be the best i guess
