Installation of the Hyper48 was reasonably simple. The LGA775 spec does not call for a HSF cage, unlike the previous P4 flip-chip spec. Instead, there are just 4 mounting holes in the motherboard for the HSF to attach to. The stock Intel HSF has these weird plunger screw-clips. You basically press the clip into the hole, turn it 90 degrees, and it's in. It's a bit tricky the first time you install one. Personally, I prefer the cage method to this.
