After Market Cooler in Old PC Installation

[Hawick]

Next year I will be upgrading my PC from an i5-6500 to an I7-6700K.

I am planning with going with a new aftermarket cooler as my PC gets hot enough as it is. My choice is to get the Cryorig M9I aftermarket CPU cooler.

Will installing an aftermarket cooler be extremely awkward (if possible at all even) in an already built system?
I have never installed an after market cooler before.

It could be completely painless, or impossible, depending on how much room your case has, and lack of/presence of any Dell-like shrouds inside, etc...

You need to take the motherboard out of the computer case to be able to install the backplate with screw posts that the cooler is anchored to.
