I just bought this mid case (corsair crystal series 460x)

I am bran new to building computers, I have spent lots of time on google about this as I wamted to make sure I could at least put a computer together before I put money aside for it.

the problem I'm having is knowing what parts are compatable with my case, can I use any motherboard, graphics etc.

the computer build I want is a liquid cool, any advice on what parts will work with my tower and if any parts will then advice on top of the line componants will be greatly appreciated, I play to have 2x 26 inc tvs mounted side by side, thanks a ton for all advice

The only thing you need to worry about is whether or not your GPU is too long, and even if it is you just need to cut into the drive bays to make space, easily accomplished with some basic tools. Since you have a mid case you probably won't have any issues though. Just measure it and take note of the card dimensions beforehand
