What are some common mistakes to look out for when putting a pc together

Check for compatibility first, including MoBo BIOS updates and minor issues like RAM heatspreader heights.
Then look how value/money it is, and how much is it better than the other options, in all aspects, like TDP, upgradibility, etc.
Lastly, a quality PSU to support the system.
And don't forget to have pizza while building it, wash hands before getting to work though.

There are some things I overlooked when I built my first PC. First, your average sub-100 dollar mobo doesn't include a wifi adapter. You'll need to buy one, and good ones are generally around $30. I can give you a recommendation if you'd like. Second, if your using a third party cooler for your CPU, it probably will not come with thermal paste. You can get some really cheap at pretty much an online computer center.

When building a PC, always make sure you are grounded BEFORE touching any of the delicate components. You can ground yourself by touching the side of a large metal object, buying an anti-static bracelet, or even buying an anti-static floor mat. If you touch a motherboard without being grounded, even a small electrical current will be able to wipe the board.

When installing the CPU, be very VERY careful. It only goes in one way, and if one pin is bent, it's almost impossible to fix.

Most mistakes occur when people rush through their build. Just take your time and use common sense. Almost nothing should have to be forced (except maybe 24 pin atx power connector or your RAM). Besides, the fun is in building it and being able to say "I built that!"
 
I bet most of you on this forum, DON'T check whether the motherboard you're buying supports the CPU you're getting.

Some people get the latest CPU's for whatever mobo and then find out that it wont go without a BIOS update.

Which is pretty much impossible to fix. Unless the mobo supports something like USB BIOS flashback.

Otherwise you'll have to go to a local PC shop and ask them to do it. Or buy a lower spec CPU then do it yourself
