That's some good reading OldChap and seams pretty simple. My case would have to be modded since I don't plan on leaving the board completely exposed somewhere. Looking around, the cables seem to be in the ballpark of ~$20 US. I doubt I build my own cable for now. I will have to keep that experiment in mind for later use.

However, since I'm gonna have to buy a new power supply anyways, I will have to crunch some numbers to see which design would be cheaper. I'm thinking probably just a larger PS. After factoring in additional costs for all of the adapters I would need to get to make my current ones compatible, I doubt I would be saving much.

Jean...waiting for the new chips to come out will only bring hope for the current ones to fall in price. Otherwise, the new chips most likely wont work with my board. Or am I missing something? If the prices is what you are suggesting, then I'm already on top of it. That is why I'm watching prices right now rather then picking one up. However, I understand you can't wait forever which is why it will be my last part to pick up. That is the deadline for prices to fall for me.

Yeah....I picked up an i7 920 for like $150. I picked up the cables on eBay that I would need to run 2 power supplies. So, the only things I need now are just that, the PS's. Right now the only free power supply not in use is a cheapo Sunbeam 450W that was pulled from a scrapped out PC. I typically use Ultra Power Supplies and will most likely start with a 700W and then get a much bigger one later as funds come up. Obviously wont be running all six off of those, but will run a couple at least.

Edit: However, I will most likely leave my nVidia 520 in my Q8200 PC since it currently runs GPUGrid and will most likely start the new build with 3 8400GS and 3 210's. The 8400's are rated for max draw of 71 watts and the 210's are rated for 31watts max draw. I will test the real life draw though as I add them one at a time to not over extend the available power at the time. I figured by leaving the 520 in the other box will help limit issues from having different class GPU's in the same box. I have noticed that a card that doesn't have the minimum video ram will still crunch if another GPU in the same box can pull units. ( I saw this at PrimeGrid with an 8400 that only had 128MB video in conjunction with one with 512MB) I had trouble with my 8400 trying to crunch GPUGrid work when I had both together as well. 8400 can theoretically complete those units, but they usually don't within their tight deadlines.

I got my CPU today with stock cooler and a nice surprise. The guy I bought from threw in a Cooler Master V8 heat sink. I gotta say that it is about 4 times the size of the stock cooler and looks like a V8 engine....lol. Good thing this will be an open system because I doubt it would fit in a standard case and certainly wouldn't want it in a tower with how heavy it is. I also got one of the two cables I ordered for the second power supply. Hopefully, I will get to start it up soon.
