Get an EPIA board, then. There's lots of people using them and doing all you want to do.
They're readily available and not horribly expensive.
You're not going to get your answer in one golden link. You need to determine how well a set of hardware is going to perform for you, plain and simple. Me, I'm a power junkie so any EPIA board isn't going to cut it.
The best performance/price setup in my opinion is an AthlonXP Mobile. P4-M boards are just too expensive.
