My 1 and only regret in the computer industry... I sold off 2 original NCase M1 v1 with serial numbers.
I needed the money as my unemployment took a toll... I wish I had at least the Silver one I had back
It physically hurt me having to sell those.
I tip my hat to you for actually building in it and using it
That depends on if the power delivery daughterboard won't interfere with the other side because of fan placement.
Same goes for the RAM sockets (SO-DIMM DDR4 btw!) if the bottom fan doesn't interfere with either of the 2 you're in the clear.
But you're still powering 10 cores with that type of cooler, it's going to be ugly.
Be aware that the 10 core CPU is 1000 USD with a normal 5 year warranty.
I get the temperature difference for your SPECIFIC case is worth it but if the memory channels break (as it can happen) you'll be proper fucked.
The NCase M1 is 1 of my favourite cases of all time in terms of simple awesome-ness but it's also a hot potato comparatively.
Combining that with a TIM-based HEDT CPU @ 10 Cores... it's going to be VERY toasty.
And if the CPU does have a failure and it being delidded... it's not going to be pretty for you.
What is it you have now? And what is it you do?
