Newly built computer won't recognize anything

Brand new parts, everything fresh out of the box. My first time building.

However while it turns on and all the fans run normally, it doesn't seem to recognize a keyboard or mouse and thus I can't get the monitor out of sleep mode for initial setup.

Everything seems to be plugged in, I've gone through the checklist and nothing seems to check out. Haven't tried ripping everything out yet and I hope I don't have to because getting it in the damn case took ages and was pretty difficult altogether.

Please tell me I didn't waste a thousand plus dollars on an expensive paperweight.

Thanks.
