Okay... Get the Core i7 920 and save some money. The i7 950 is not worth the extra money.
GPU: I would recommend getting the HD4890 or GTX 275 and wait till to see what comes from the DX11 cards before spending all the money on a GTX 295.
RAM: I would go with the OCZ Platinum DDR3 1600.
PSU: I would go with at least a 750w PSU from Corsair or PC Power&Cooling.
HSF: I would go with the Xigmatek Dark Knight S1283V or the "TRUE".
Case: I like either the Antec 1200 or Cooler Master HAF 932 for full size cases and Antec 902 or Cooler Master 922 for mid size cases.
Sorry no links on my choices but I typed this from my IPhone... not around PC at the momment.
