I run my 920 and my gtx 260 of the above mentioned corsair psu and have no dramas 3 x hdd and optical drive etc Coollermaster storm scout seems like an alright case
I would recommend getting that monitor here and saving some money. Also, I recommend going with a full-tower case like the Antec Twelve Hundred instead of spending that much on a mid-tower case. Lastly, I recommend avoiding the OCZ PSU, since it's based on the FSP Epsilon design, which has out-of-spec ripple near 80% load and above. The Corsair is a much more reliable product.
If you live near a microcenter, you can grab the I7 920 their for 200 dollars, and if you know the s-spec numbers of the D0 stepping, you can request those same s-spec to ge the D0 stepping.
