Ace-X,
I agree with you that it is a possible job and it can be very valuable to learn how the PCI works and I did not wanted to discourage sztibi82 from doing it. Even though PLX makes the design much simpler, it is really big job for such a small requirment, unless it is for Pure Academic Knowledge.
IMHO that circuit can be done in a few weeks time using USB, but it will take 3-5 times more doing it on PCI, so maybe I said it in a wrong way, but for a hobby project, PCI is way too ambigious but the rewards are much greater than USB for example.
just my 2c,
