My current disaster inventory:
Table of Contents
1. Power (unresolved)
2. Data (unresolved)
3. Audio (unresolved)
Nested list of horrors:
- 14ft HDMI coiled behind monitor
- sub-item: coil diameter violates manufacturer spec
- sub-item: heat retention concerns per my earlier thermal analysis (as I mentioned above)
- USB hub daisy-chained to hub

I will upload photo when I locate camera under cables.
