Thanks for all of the replies, especially to Ben, I will take your advice
and keep looking for an "ideal" combo, with the key being FREE. I mean,
anybody can spend money and buy somebody elses hardware, but understanding
what is happening in that hardware can be difficult if you are not familliar
with what you are using, which would be the reason why I need to build.
Again thanks for all the assistance, this is a great list:)
