EEATX vs EATX

[darkconz]

I have a SuperMicro SC216 case in the way and I am sourcing a motherboard for it. One of my local guy has a SuperMicro board that is listed as EEATX (enhanced extended atx) form.

But the chassis says only EATX boards are welcomed. Will the EEATX board fit given both case and motherboard are SuperMicro.

Thanks

If a chassis is specified as E-ATX then EE-ATX will not fit, it's too large.

FYI more info: ATX - Wikipedia

EE-ATX
Supermicro's server motherboard's measuring 13.68 × 13 in (347 × 330 mm).

E-ATX/SSI EEB
Although true E-ATX is 12 × 13 in (305 × 330 mm) most motherboard manufacturers also refer to motherboards with measurements 12 × 10.1 in (305 × 257 mm), 12 × 10.4 in (305 × 264 mm), 12 × 10.5 in (305 × 267 mm) and 12 × 10.7 in (305 × 272 mm) as E-ATX. While E-ATX and SSI EEB share the same dimensions, the screw holes of the two standards do not all align; rendering them incompatible.

Noted.

The reason I ask is I was browsing on Supermicro's site and I encountered this document:

https://www.supermicro.com/manuals/brochure/x9_HeatSink_Compatibility.pdf

X9DR3-LN4F+ being a EEATX shows compatibility with SC216BE16-R920LPB. I guess 13.68" x 13" is their definition of EEATX? Does anyone know if the mounting holes are the same?

The hole pattern is the same but I belive that it needs extra space at the top of the board which usually there is a power supply in the way if the chassis isn't designed to accept the EEATX.

There have been several revs to the SC216 over its lifetime - YMMV - but the following is generally true...

a) There is space for the extra width board (EE-ATX or CEB) in the SC216 chassis.

b) SC216 has relocatable MB moints and can accommodate almost any standard - and many SM proprietary - MB mount point configurations. Both EE-ATX and CEB can be accomodated.

I guess I shall wait for my case to arrive before buying the board. Otherwise I would just end up with something not being able to go in.
