The Intricacies of EE-ATX: A Supermicro Motherboard Layout

Over the recent months, our Engineering Team has been busy building Superclustr's first generation Open Source Supercomputing Workstation.
A tremendous amount of engineering is being put into ensuring that each part of the appliance is thoroughly tested for safety, efficiency and compatibility.
Following through all of these requirements, our Engineering Team writes about our research and experiences in this field.

Debate over the Enhanced Extended Advanced Technology eXtended (EE-ATX) Motherboard Layout

The Enhanced Extended Advanced Technology eXtended (EE-ATX) Motherboard Layout has been stirring lively debates in Forums and our Engineering Team.
This unconventional piece of specification was introduced by Supermicro, a provider of IT Solutions that isn't afraid to challenge traditional norms in technology design.

Understanding the Unconventional EE-ATX Layout

EE-ATX stands for "Enhanced Extended Advanced Technology eXtended". It's an unconventional move from Supermicro to step outside the standard
motherboard layouts. This layout design innovation confronts the standard assumption that all motherboards will neatly fit into case standoffs.
Consequently, this unconventional approach adds a new level of complexity when it comes to selecting compatible hardware components.

Taking on the EE-ATX Challenge

The introduction of EE-ATX and the complexities that come along didn't deter us; instead, we found the challenge stimulating.
We even ventured into building our first generation Workstation using this unique format. We decided to document our experience and share our journey,
which was filled with technical hurdles, countless recalibrations, and a voyage into proprietary territory.

Choosing the Supermicro X9DR3-LN4F+/X9DRi-LN4F+ Motherboard

We selected the Supermicro X9DRi-LN4F+ as our reference point and Motherboard of choice. This particular model is infamous for its non-standard alignment.
The Motherboard's quirky reputation as the "Does not fit into my EATX" board has become a humorous anecdote due to the numerous forum posts
with buyers being confused about the board refusing to conform to the conventional EATX dimensions. This inside joke, though humorous,
underlines a real problem that many enthusiasts face when trying to integrate this board into their systems.

Designing a Custom Chassis for the EE-ATX Board

Once we took on the task of accommodating this 'unruly' motherboard, we meticulously reverse engineered every mounting hole position
for the EE-ATX board. This groundwork enabled us to craft a custom chassis designed specifically for the EE-ATX form factor,
proving that even the rebellious "Does not fit into my EATX" board could find a home.

Sharing Our Findings with the Tech Community

We have made our mounting hole measurements publicly available, offering a much-needed resource to the tech community.
We believe that such challenges are opportunities to innovate and break barriers.
