This is my first Intel build. My previous build was a AMD 965 and 2x GTX 560 Ti's in SLI.
About the HDD's: The Seagate was a random hard drive in my house and I accidentally bought the 5400 RPM 3TB insead of the 7200 RPM (oops).
When I built it late at night, and I tried to run it, there was no BIOS displaying, nothing. I checked everything, couldn't find the problem. I took it to a specialty store this morning, and after going through everything, he took off the cooler. At first we thought the CPU was fried cause it was barely covered in thermal compound - but, it was stone cold. Then we checked out the socket, and there were a few bent pins. I was prepared to either buy another Sabertooth Z87 or send it to ASUS in Ontario (I live in BC). The employee then decided to try and bend the pins back with a sharp knife (the kinds that you would use to open small boxes or build miniatures), after about 30 mins of that, we crossed our fingers and hoped that it would work. There was so much tension in the store, they were waiting around and as soon as we heard the beep we had a big celebration.
