What's the problem with ATX?
Why would I want a psu that adheres to intel standard?

So unless I want to brag about how accurately my psu can supply 12V, I'll be fine with an ATX.
Getting my printer together becomes increasingly tedious with contrary answers in this forum. =(
Any ideas on the motor cables?

Biggest issue with generic PC power supplies is that manufacturers tend to over-state the current limits that they are capable of, even the big-names in the Gaming PC after-market have been known to do it. eg: A PSU might be capable of providing 20A on 12V, but only if it's drawing 1A on the 5V rail at the same time, and ONLY if it's on clean power.
Server power supplies usually work regardless of the load on other rails, and usually have a wide tolerance on their input voltages. Additionally, they usually don't have extra circuitry to generate rarely used voltages that are part of the ATX spec (such as -5V and -12V).
eg: An ex-IBM server AcBel brand PSU I have generates 12.2V @ 48A max and 5V @ 0.2A max ONLY - no other voltages. I've tested it and it definitely is capable of the amounts it claims.

IBM/HP is not interested in sending out staff out there every week at 200-1000bux a pop just for labor.

Sounds like you are buying cheap servers. Every IBM server (and network switch, SAN, and similar rackmount equipment) that I've purchased in the past 25+ years has been configured with dual hot-swappable power supplies. When one fails, they FedEx out a replacement because it is a 15-second swap that they expect the customer to perform. To IBM's credit, I have only had one server power supply ever fail, and it was a crappy tower box that should have been labeled as a desktop.....
