Can't get ex58-ud4p to do anything

I just recently bought some parts in an attempt to make a computer.
The parts I have are as follows.
Intel Core i7-920 processor
Gigabyte Ex58-ud4p motherboard
BFG Tech Maxcore 55 (nvidia geforce gtx 260 graphics card)
Corsair Tx750w Power Supply
6GB (3x2B) OCZ 1600 DDR3 ram
Seagate 3.5" Barracuda Hard Drive
CoolerMaster 932 HAF case.

I have followed the instructions (or so I think) in assembling the computer, but I am not even able to turn it on. I don't get LED lights or anything, I'm not sure if there's something wrong with the power supply, or if it's wired incorrectly or what. The labels on the CoolMaster are also rather confusing.

If anyone has used these parts before, and could give me any advice at all that could help, I would greatly appreciate it.

I have downloaded the manual for your case (which, by the way, looks like a really nice piece of equipment); if you could post a bit more detail regarding your actual problems with it I can help you out; you may, however, want to do some limited testing while 'out of the box' to check some of the basic things and getting them running before moving them to the case...

I didn't see that page before, but I found the problem.

I had the 24 and 8 pins connected, that wasn't the problem.

The instructions for the case contain very little words, but I found out that I needed to put in brass connectors before I screw in the motherboard.
Everything works now, and thanks for your help.
