1RF Box Removal - Part 1
Remove the old heatsink,
then pry off the bottom lid of the RF box with a small flat head screwdriver.
2RF Box Removal - Part 2
Unsolder the five pins on the bottom of the PCB. You must get all of the solder off. I highly recommend a large desoldering pump like the OK Industries DP-100.
Now flip the board over and remove the solder blobs that connect the top of the box to the mother board. Again, make sure to get it all. I sucked up most of the solder with my desoldering pump. Then, I followed up with some solder wick.

Take a flat head screw driver and slip it between the motherboard and box and gently separate the box from the motherboad. If you didn't get all of the solder off, you may have to heat some of the pins up with a soldering iron while doing this.
