Computer won't turn on after Case switch.

I have recently bought a new Case for my Computer, mainly for Airflow and aesthetics. I had a (relatively) cheap mid-Tower - Cougar Solution AF-2. I purchased an Aerocool xPredator Evil Black Edition.

Yesterday I transferred my rig into its new Case.
When I turn it on, it simply doesn't do anything. I sits there Hardrives spinning up, case fans and Graphics card also spinning.
I don't get to the BIOS, simply a black monitor that doesn't recognize a source.

My rig:

Motherboard: MSI X79A-65GD
CPU: Intel i7 3930K over clocked to 4.2 GHz
GPU: AMD Radeon HD 7970 GHz Edition Sapphire Vapor-X
RAM: 32GB Mushkin 1600MHz Blackline 994050 (4x8GB)
PSU: Cougar GX1050/R 1050W
CPU Cooler: Corsair H80i (with two Noctua NF-F12)
Boot SSD: Mushkin Chronos
HDDs: 3x Seagate Barracuda (varying capacity and age)
OS: Windows 8

The computer worked flawlessly before the case switch.

The POST display on the motherboard states b0 (might be 60, can't tell for sure).
I reset the CMOS, switched the BIOS from A to B, disconnected everything that wasn't vital, reseated the RAM, reseated the Graphics Card, reseated the processor, used only one Stick of RAM, all to no avail.

I will take the entire computer apart again and try to get it to POST outside of the case (I will lay the motherboard on some paper towels on my desk) later today.

But I'm at a lost here. Any help would be greatly appreciated.

    Well...if it worked before, and it doesn't now, something did not get reconnected correctly.
  2. It’s probably shot in the dark, but try to put an old PSU to new rig and start it. If it starts you will know the solution. Try to clean MEM and GPU contacts and them plug them again.

    I'd disagree with that route. He had a fully working PC. Took it apart, put it back together...now it doesn't work.
    The only thing that changed was the construction, not the parts (except for the case).

    What would have caused the PSU to go bad? If he tries it with a different PSU, that is introducing another variable. Construction + new PSU.

    I assumed that he put new PSU to case, so for that reason I put mu answer.
  5. Recheck power, reset buttons if they are correctly plugged in on MoBo.

    I took the Computer apart and reassembled it on my desk.

    It is now working again.

    Now all I will have to do is put it back into the Case and pay extra close attention to what I'm doing.

    Photo evidence:

  8. There ya go. All parts working, now just to get them working inside the case.
  9. Now just carefully put components into case. Good luck!!
  10. I got them working again. Thankfully.
    Still don't know what went wrong the first time.
    I'm just glad it is all working now.

    Thanks everyone for your help.
