Keep in mind that he can change the configuration if he wants. The site I used does let you choose stuff like "single, double in RAID0, double in RAID1" and such for HDD's and for video you can choose single or double.
But choosing such options would push it over the $1,400 budget he has.
I went back to the site to see how much more the 5850 would be over the 5770. He would have to add $122 to upgrade the card. I personally with how easy it is to upgrade video cards go with the 5770 now and then later on upgrade to a card that is not even out yet. Say a 59xx or 60xx type card.
The 300 GB WD Velociraptor would be an extra $156 to get 700GB less capacity. So then you would want to have a 2nd HDD of at least 750GB to add on top of the $156 that he would already be spending on the Velociraptor for at least $75 more or $99 for 1TB.
Many games now a days take up 10GB or more in HDD space so you would put only be able to put the OS and critical programs on a Velociraptor.
Also of note for fcar79, you may want to wait a few months before you get your computer. Use a cheep used computer in the mean time but company's are already starting to advertise their USB 3.0 expansion cards and Gigabyte's UD6P line of motherboards already has a kind of "pre-USB 3.0" and "pre-SATA 3" on them (you have to turn PCIeX16 to PCIeX8 to get them to work from what I read) so holding off a bit more could net you a computer with such tech's built into them. USB 3.0 is rated at 4.8 Gbps and SATA 3 is 6Gbps.
I was just reading some of the pages at
www.everythingusb.com on USB 3.0 and it was talking about Asus, Gigabyte, and Dane-elec all starting to ship USB 3.0 stuff this month.

Also for a monitor, NewEgg has a very good Asus one on sale until 12/16. It has a dynamic contrast of 10,000,000 :1 and a response time of 2ms. $190 and free shipping. Just be sure to read the reviews as it looks like ATI cards have a setting you need to tweek to prevent the problem the guy who gave it the 3 egg score had.

Edit: Oh ya, almost forgot. On the Intel system (don't know why not the AMD) the site I was at offered to factory overclock the design. 10% for $19, 20% for $49, and 30% for $99. Also when I read a review on the
Thermaltake SpinQ at OCC it did good in the stock tests but lost ground in the overclocked tests. I would personally suggest adding the rig to you cart and then calling or emailing the site to ask them to switch it to the Cooler Master V8.
