Need help completing my rig

[dpapag]

I was given some old parts by a friend, and I'm wondering what else I'll need in order to get this all setup.

EVGA 122-CK-NF68-A1 LGA 775 NVIDIA nForce 680i SLI
Intel Core 2 Quad Q6600 Kentsfield 2.4GHz 2 x 4MB L2
CPU Fan: Arctic Cooling Freezer 7 Pro
CORSAIR Dominator CM2X1024-8500C5D (4 sticks for a total of 4GB)
CORSAIR CMXAF1 Fan
GTX 260 Sonic 216SP 896M DDR3 448B (2)
Antec Nine Hundred Black Steel ATX Mid Tower Computer Case

No cables, no HD's, no DVD burner, no OS, no power supply.

1. What type of power supply do I need to get in order to run both video cards effectively?Will an Antec CP-850 fit the bill, or is it overkill?

2. Is there any thing else I would need to run the 2 video cards at once? Doesn't look like there's enough room on the mobo to fit both of them. Is some kind of adapter needed?

3. Anything special about today's DVD burners? I figured this would work:

4. For the HD, I'm thinking 1 TB will do the job.

5. Cables for the HD - Are these correct?

6. OS - Windows 7 professional 32 bit

I'd like to be able to just order everything I need at once and install it all. Is there anything overlooked?

For the hard drive and the dvd burner you might as well get a combo to save some cash. No reason to waste money.

For the power supply you can save a bit of cash and in my opinion get a much better one like this.

Personally, I have never in my life bought a windows disc. You can download windows 7 from about 96 million different places and save yourself the cash. Nowadays it's so easy to find software on the internet that it's usually a waste to buy it new. If you are afraid of viruses etc PM me.

The hard drive and dvd combo both run off sata cables. If you don't have any I would grab 2 of these.
