So basically, I have no clue on how to fix/build a PC, as this is my first one, but I was just wondering, are all these disconnected wires normal? I went into my garage to avoid any ESD so I can take these pictures. This is how it came, it runs perfectly fun and runs like a wonder but im just gnienuly confused on if I should be worried or not with these wires being disconnected...

The pictures for some reason got rotated so I hope this helps to clear any confusion on what youre looking at, thanks for any and all help.

Hello @Feedvro 

Everything looks normal. The photo marked Fan I think is related to a liquid cooler, but you have an air cooler so it wasn't needed. The photo marked Graphics Card Wires is just a second set of power pins, if you were to install another card and it needed them. Your current card is connected as is. The photo marked Side Panel is just a second set of Sata Cable data and power connectors. If you add an additional hard drive in the empty slot, you are already wired up.

As you said its working fine, so you are good to go.

All is normal as the expert said, all those cables are for a liquid cooling solution, more powerful GPU that needs 2xPCIe connectors and extra storage, enjoy your computer.
