Summary

What amazes me is the durability of this unit other than the original power supply. When drilling these large holes I spun out the HD1000 a least three times whacking it against tools, dish racks and the cat.

The case is a little kinked; the front scratched and scuffed. I didn't want to mess with removing the mainboard for this procedure, I didn't want to deal with the interface connectors and ribbons. I shook out and shop vac'd most of the metal shards from drilling.

Exhaust temperature about 18F warmer than ambient.

Most of the heat probably coming from the PS.
Most of the heat coming from VR regulation chips:
u23:TP58 - 2.5V
u20:TP45 - 1.8V
u12:TP29 - 1.5V
last one is the one to prone fail as it hold a current around 2 A (!) and all the VRs feed by +3.3V rail.
Wow - that's a lot of heat coming off those VR chips!
