If you want a non-standard heat sink, Hyper 212 is good.
If you want a DVD drive, the Asus 24x is good.
If you need those things, you may want to try to go $50 over the $800, because that is already cutting a lot of things pretty deep.
Scaling back the PSU, going with a lower rated DVD drive, and going with no hard drive seems like a pretty tough thing to do to include the HSF and the DVD drive.
Are you sure you don't need a hard drive, by the way? Do you already have one laying around that you didn't mention?
If so, it would be easy to cut out the $85 hard drive I chose for the other person and include the Hyper 212 and the better Asus DVD drive and the better other parts all around. 560ti instead of 6950 is nbd since it costs the same and all.
Also, if you are buying these parts for your own use, you should know that your Windows license will not be legal.
There are only 3 legal options:
1) If you are a student, get Windows from your school or from Microsoft Student website.
2) If you have a legal copy of XP or Vista, you can get an upgrade CD.
3) Retail full version non-OEM CD.
