A few questions about this new version:
Will there be an option for right-side-up orientation with a more normal top panel? This edge-to-edge big hole design is good for cooling 400W GPUs, but aesthetically it looks bad imo, and lets you easily see everything inside the case, which in the default orientation will be an ugly GPU shroud.
If there won't be an option for right side up, will you offer a dust filter for the top? Big holes + GPU on top means lots of dust going inside.
Will the side panel now really just be a big mesh? Will there be an option for a normal side panel? (vented, not a window). I like to use ultrafine filters, adding them to the mesh would restrict airflow too much. And aesthetically it looks worse imo, and is also bad for transportation.
Suggestion - I think the front I/O would look better with the two Type-A ports on one side and the two Type-C ports on the other side. And I definitely think there should be a 3.5mm headphone/mic jack, lots of people still use those. Just get rid of one of the USB ports, 4 is overkill imo.
Do we know the dimensions of the case? I'm a little confused because from the pictures it looks like the only dimension where it's larger than the M1 is the length. And yet it fits a mATX board and a rear-mounted ATX PSU, how is that possible?
Will the case be aluminum? Not just the panels but the frame as well?
It's so much longer than the M1, is it really worth increasing the length this much to accommodate the 1-2% of people who will want to buy a GPU that's longer than would fit in the M1 V6?
Finally, I'm not sure about the name. Doesn't Evo usually mean a budget option? It stands for evolution, but it's usually used to mean lower-end model from what I've seen e.g. Samsung EVO series of SSDs and the LG EVO line of OLED TVs. This case is very different from the M1, so I would call it something different. Honestly, no offense, but I think if you just restarted the M1 V6 it would sell better than this case. Otherwise, I see the C4-SFX partially filling the niche that the M1 occupied, more so than this M1 EVO. The latter compromises too much for the sake of effectively cooling $1200+ 350W+ GPUs that almost no SFF enthusiast will buy, in my opinion. Even with the 40 series, cards under $1200 will use no more power than a 1080 Ti.
The M1 was already great at cooling power hungry GPUs, even 320W was no problem. It had this killer feature where you could deshroud a GPU and then use your bottom 120mm fans (possibly with 10-15mm ducts that can be found online) to directly cool your GPU heatsink. That was an elegant and effective solution that also solved GPU sag, lowered noise, and managed dust discreetly. Here that's not an option, and it doesn't seem like you can even mount fans to the top unless you screw them directly to the top panel vents.
Sorry, I rewrote this post 3 times to make it less ranty and still failed. I am just upset at the state of SFF these days. I am holding onto my M1 V5.1 for dear life, I consider it to be the best-designed case ever and the peak of M1 development. I already had issues with the V6, this iteration takes the design even further into mesh box territory, the next version will probably not even have panels.
