The assembly of the parts went very quickly. Maybe a few minutes at most, only taking longer because I was taking pictures the entire time.
Heatsink, make sure you remove the thin plastic tape covering the heat transfer medium. When you install it make sure it fully covers the CPU, the ram will not get hot like the CPU, and if you only partially cover the CPU then you will not get the full heat dissipation possible. The heatsink attaches by simply pushing the plastic clips through the holes in the board. Very clean and easy install.
