So then tell us...what prices are you able to get on the parts I listed? If you're proposing different components then please list your alternatives. Iagree that the parts listed are on the upper end and a decent system can put together for less but I listed the components I used and the current prices. Your post doesn't help anyone.
I solved all these problems already.

$5k is way overkill.
