What is PCB exacly, when talking of graphic cards?

[Slipperss]

I have heard that "PCB" so many times. I googled it, and i am still clueless.

I need to know because I have installed two water blocks on my graphic cards, and heard that you must be careful not to bend it.

So tell me please, what is a PCB, and what does it look like?

So its basicly the whole thing?

Just crapping myself pretty hard over here, because as i was walking in my room, I heard this loud "crack" which sounded like it came from my computer which is in the middle of my room, could of been the floor, hoping for it, but you never know. I am waiting to leak test it, as i need a few more fittings. I'm just afraid that i tightened the screws too hard and something snapped inside it or anything. Sadly I'm unable to leak test it till at least Wednesday :S

Not the whole card, just the red/green/black/etc part that everything is attached to. Its the circuit board.

Well, can always open the case side and have a look. Should be fairly clear if something cracked.

PCB, a thin plate on which chips and other electronic components are placed. It is a place to mount the components and it provides the means of electrical connection between the components. It is used in electronics to build electronic devices.
