"Fan" Failure
HP PC reported a fan failure and would not boot. Trouble shooting showed failure was power out on the motherboard fan connector. First picture shows slice to pickup power from one of the SATA power lines. Second picture shows connector sending tach signal back to "failed" motherboard fan connector. Power out from this connector was bad but it still recognizes the good tach signal and now proceeds to boot.

Access Window Concept
This is an illustration of an access window to allow access to the back of an equipment table. I invite comments on the advantages of such an access window versus a rack mount like I am using in the cave. The rack can be easily moved around with access to the rear.
