Thanks for resetting me. Don't want to get someone else caught on this. I have a LSI card I was going to use (just to use up some parts) but got distracted by the MiniSAS and forgot it was just a connector spec not a signalling spec. Well I can play with breaking it out later for something...

16 SAS/SATA across the two MiniSAS (or NVME, options...), plus oculink, plus 2 onboard SATA ports plus on-MB NVME. Either way all the systems I can find (pre-built, not OEM) which they put this board in have like 2 drive bays. Clearly they want other people to build systems with this board.

Nice. I do something similar. I print out some cross sectional slices a couple layers thick in solid and use it to judge fit and how things will look. Using silhouettes like this has often saved a lot of time and allowed me quick visualizations of stuff that won't work before I go whole hog...

I mock things up with construction paper and tape just to check gross clearances then I model it up for 3d printing. Might have been faster at this point if I modeled the entire chassis with MB in it and just built it from there but I like working with my hands and tools once and a while. ;)

Correct, which is why I wanted as much space between the fan and the top of the heatsink to have a pressure normalizing plenum style space to push air more evenly into the cooler. I can reduce that to between 5 and 7.5mm and then the original delta fan suggestion should fit without undue...

I'm mocking up the 40x28 option currently in fusion to see how it might look. Might be able to make that work with horizontal airflow with a switchback plenum design. SMicro optimized the ever living hell out of this MB for reasons I don't really understand. It's only available in 1U chassis...

This board/case combo unfortunately won't give me space to do that. too many things in the way for it to fit

Yeah, I was kind of hoping I could avoid that path but I may just check clearances and built that. Then I can open up some rather ridiculous realms of airflow.

Replacing the heatsink is also a viable option if one can be found with a matching mounting screw layout. I've struck out there so far.

Quiet was pretty much immediately discarded from consideration. ;) My rack is out in my garage so I'm not bothered by noise. Is the ~10mm of clearance above the fan likely to be sufficient to not restrict airflow? I guess it will be inflowing from all sides.....

So I got this board via a bailiff auction and want to use it for a combined homelab/NAS application. I have a 2U case and I am having huge challenges keeping the CPU cool (still working on building a new duct and improving case fans for more static pressure) but I would also like to pursue a...

Buy enough and everyone is willing to accomodate. Is the ~30 seconds before the system POSTs normal for these units? I nearly threw out some RAM cause I thought it was bad, but no system just took forever before it would beep and present BIOS.

JUST after I received my units. Doesn't it figure..... I hope someone offers the rackmount chassis sans MB so I can just move over. That is a much better form factor for me.
