White Paw is so right. You dont have to water cooled the VRM/Mosfets (crosschill) or the Z87 chipset ,or the ram. It so fun to do it and it looks so kick a$$. If you go that way it will cost around $1000 to $1500 for everything. You need all the water blocks, from full boards sets, cpu, ram, gpu. Then at least two rads with the fans, water pump, fittings, tubing and res. You have to get the right water block for the hardware that you have and you need to know what size rad your case will hold. If this is your first time water cooling then I would go with a kit. You can get a EK or XSPC for around $200 to $300 and it have everything you need to get started. Then if you want to cool the video card then you can buy a water block for the card that you have and add it to the loop. Just get all the hardware together and what kind of case you are going to use and how much you can spend on your water cooling setup then list them and we can help you get a good setup.
