My custom PC will turn on, but no output

[penapox]

So, I have a mini-itx pc that I built about 2 years ago. It was working perfectly up until now. The case I had it in was wayyy too cramped, so I decided to get a Bitfenix Prodigy. I connected all the wires, put in my ram (8gb), and tried to power on the PC. The fans turn on, the optical drive opens and closes fine, but nothing shows up on the screen. I'm using HDMI. I'm sure all the components work as they worked before I switched cases. I tried the disconnect-everything-except-for-ram, cpu, cpu fan, and psu method, but the same problem showed up. The power leds light up, and the power button works, so that's not the problem. I have a backlit keyboard that has a little animation when my comouter starts up; it does that animation, but after, the keyboard isn't responsive. The caps-lock light doesn't turn on.

Have you accidentally plugged the hdmi into the motherhood instead of the GPU? It's a common mistake people make.
