Yeah, i just realized his account is gone and i've no way to contact him. It was sad and sudden, but it's okay, we can still see what he said even though the images are gone..
And yes that is an S4 Mini, specifically the original one, now known as the S4M-C "Skyreach 4 Mini Classic" made by NFC, we have an entire forum section for that Case found here , and it's actually my case of choice, you can see my build thread here.
The old case thread for the S4M-C is here (note this one is out of production and only a limited number exist)
the new case known as the S4M thread is here (note this one is currently still in production)
Thanks, again, a lot of helpful information. One question I have, which I'm not sure about is, how is the Case Design of the A4 "Classic" is? As I've seen from the images and builds, the Side panel of the Case actually goes over the Metal housing.
This is important to me since if it is the case, then the Fan MOD will not be applicable to my build, as my side panel is recessed into the case.
So I have exactly two slots of Height to tinker with the Cards cooling, while in A4 it seems you have an extra ~2mm, which is just enough for the Noctua Fan Mod.
Found the Scythe Slipstream Fans, I have heard from them a few times already on other Forums.
They just have a height of 12mm, which should do the job, will buy two for now and conduct some testing
