This will save you enough money to get an 8800GTX over a GTS.
i considered the p5n, especially since its basically the striker without the bells and whistles and a little bit of hardware, i may still go with that board though
im not keen on 4x1gb as until now ive been an amd guy, a lot have said that its no problem with intels, but it just rubs me the wrong way and i feel it will be much easier to keep 2 2gb sticks stable on an OC than it would be 4 sticks
about the PSUs, they need to be as silent as possible, anything with an 80mm fan will not be usable in this system since the main goal is silence, as it is the silverstone will be the loudest thing in my case (except maybe the HDDS)
and finally the GTX is also not an option as it will not fit in the case
