Could probably drop 100 of the price by using a used 4850/70 off ebay.

Don't crap out on the PSU. A bad PSU will likely mess up your other parts, which are pretty valuable.

Something like this might work well for you.

Edit: Missing hard drive, optical drive, and OS. I'm assuming you have that covered...

Sorry I must've missed that part in the beginning about you building it for other people. I don't know what the third party's budget is, but this build would likely handle most new games pretty well.

I personally like the challenger. I used it for my work, for a budget video editing system and it fit a refurbished NVIDIA PNY GTX 470 along with a Firewire PCI card okay. I also loved the way the hard drive mounts where setup but honestly, if I had the extra cash in the budget for my works build I probably would have went with the Cooler Master case as well.
