This will be going into steps with pictures and videos of what i did step to step. A lot of steps vary from one person to another. I did the way I felt most comfortable with.
A lot of people like building on the motherboard and then putting it in the case. This is what I just did.

im using a I3-9100f CPU
4 cores 4 threads 3.6ghz Align the bottom left triangle to the motherboard. (Make sure its seated well) it should not wiggle or move a ton. I didn’t have extra thermal paste I just disassembled my PC to make this project. However, if i did have thermal paste i would’ve used it.


Push down the latch to fully put the socket in place.
Specs: DDR4: Version 4 32GB: amount of storage/capacity 2400HMZ: The actual speed of the RAM. CL 15: latency to request data
Just a cheap Air cooled heat sink to cool down the CPU during intensive stress. 4 spring screws to lock it down in place.

This is probably the easiest thing, all u have to do is align the cpu fan and put on the metal brackets to hold it in place, no screws needed for this part. the brackets hold onto the actual heat sink.
