Step 1: Parts
The rest of the instructable we will be working with the 16 mm and soon I will post one using the 10mm bolts
My Parts List:
8) 16mm m5 machine bolts/ screws
24-32) 5mm flat washers, steel
16) #10 flat washers, nylon
10 tube of heatsink paste
1) bottle of Everclear or 2 step Articlean
13/64 Drill Bit
screwdriver (one that matches the head of the m5 bolts. I have flat headed ones)
small (really small) flat headed screw driver
1/4 nut driver or pliers
Step 4: Drill out the case
Drill out the holes in blue
remember to clean out the filings / deburr the case
Step 6: Remove heatsinks
remember cpu is the tall heatsink that covers a single die while the gpu heatsink is flat and covers a large die and a small one.
use the nut driver or pliers to remove the studs from the underside of the heatsink
Step 8: Ring toss anyone?
Do this for all 8 bolts.
Be warned the nylon washer are a pain to get on the bolts
Be warned 2.0 the position of the nylon washers is crucial to preventing shorting( I tried without them and my xbox wouldn't turn on until I added the nylon washers.)
