Very nicely done !!! I'm sure this will help with air flow also. Do you have any tests on the thermals of your components under load? I'm looking at the A40, for a mini workstation build. I'm going with the R7 2700 (8C) with NH-L9i. I can easily use a entry level Quadro P620/1000 or Radeon WX 3100. Both are half Length cards. What I'm concerned with is heat and noise. It appears that using a SUG 300W brings with it lots of fan noise. Yet, going with the HDPlex 400 AC/DC and a HDPlex400W DC/DC brings a much higher price to the build. I would appreciate any feedback, since this is my first mITX build, and I have not built a system for about 15 years.
i don't have precise measurements and unfortunately i ended up selling the case after all, lol! i'm OCD about my computer build and i couldn't stand having to dismantle it all at the slightest hardware change, and also the fact it was a bit flimsy because of the mounting mechanism, and also, DUST MAGNET on those panels!
i recommissioned my Lian-Li PC-Q21 and modded it for airflow (2x92mm fans on top) otherwise it was a literal oven.
but i can tell you i had ZERO temperature issues with the A30 using the HDPlex 400w. temps were cool and when gaming or under load, the heat was rising up super easily and exhausted as it was created. i have a bit more heat issues in my Lian-Li, but it's under control. i certainly felt safer with the A30 as far as temps go. i'm positive the A40 must be a good choice with very similar thermal management!
