Depends on the age. If it's brand new (i.e. weeks not months), $1,000. If it's more like months old, $800-900.
The problem is that while you've got some nice parts in it (i7-930, 5870, Hyper 212), you've also got some very low quality parts in it (board, RAM, PSU). You also have some lower performing/overpriced parts (HDD). And frankly, I can't even find that RAM or case on Newegg, which is not a good sign.
