Btw, if I ever wanted to change motherboard what would I have to change in my system? Would there be any data lost or anything? Or just some drive installs?
I am a bit late to the party but..
1.) If you change motherboards you need to make sure your OLD CPU is compatible with the new one.
Different motherboards may have different socket types.
2.) A new motherboard may require different RAM. You can double check the new motherboards manual to get a list of compatible RAM.
3.) As ScathEnfys mentioned above, you will not lose any data.
Your data is saved on your hardrive(s).
Yes I did finish my last post. I was using pcpartspicker and they told me that I needed a CPU cooler for Intel i7-6700k so I added a 25 dollar one
I would get a better cooler. The CPU is like the brain of your computer, if it overheats you can have major problems and even damage the CPU.
Cooling is very important when building your own computer.
For example, the computer I use, has a giant N-14 Cooler. Now this one is a bit of overkill for your build, but it emphasizes the importance of having a good cooler.
Also, my computer has a total of 9 fans. Your computer may not need as many but you definitely want at least 1 exhaust fan for the back and top of the computer, 1 fan in the front that pulls in air and possibly a few fans that pull in air from the side.
Many of these fans will come with the case (Chasis) you buy. Your comeputer case has the biggest impact on things like cooling, noise and protection of the various computer parts.
How can I check if all the parts will fit in the case?
To be honest you will have to read through the dimensions of each part and figure out if they fit.
RAM will always fit, but when it comes to sizes the most important aspects are as follows.
#1 Buying a large enough case.
#2 Choosing the right size motherboard. Motherboards have different form factors that decide how large they are.
#3 Choosing a videocard that fits.
#4 Choosing a CPU cooler that fits.
(Sometimes CPU coolers get in the way of your RAM, since good ram usually comes with heat spreaders, which add additional height to the RAM.)
#5 Choosing a PSU that fits. (This usually isn't an issue but if you have a smaller computer case, this could end up being a problem.)
Usually I start by choosing a case and motherboard. Then once I know the dimensions of both, it allows me to more easily check if everything fits.
If you really are nervous if everything will fit you can always buy a very large case. Two well known, high end cases are The Coolmaster HAF 932 Advance and Coolmaster HAF X. (These cases are as big as it gets.)
