what's the point of making it bigger?
Now (140mm) it sits just in betwenn a Dan A4-SFX (112mm width) and a NCASE M1 (157mm)...
- You want a low profile CPU heatsink? You buy Dan one,
- You want a taller but not too tall heatsink? You "buy" a Louqe one,
- You want even taller? NCASE!
- You want AIO? Either NCASE M1 or Louqe...
...
I understand your argument, the problem is the new CPUs + GPUs coming out, higher TDP and bigger size.
Intel is putting a 8C/16T i9-9900K mainstream (prob ~140W at load), Nvidia decided to release a dual fan Ref GPU at higher TDP, forcing board partners to make 3 slot GPUs, and many bigger in all dimensions compare to last gen.
The advantage of supporting a 58mm tall CPU cooler vs 48mm is marginal with 9th Gen Intel and Ryzen 2nd Gen. That's why the A4 V3 *had to support 120mm AIO. If 58mm CPU cooler was enough, A4 would just be wider at 140mm.
In order for Intel and Nvidia to compete with AMD, they both decided to forgo power efficiency in favor of performance. Hotter and bigger component is the trend now, it's a problem for all SFF cases.
So my point it, this middle ground between the A4 and M1 is shaky with the new hotter and bigger components coming out.
Increasing overall dimensions, increase cost which is already high... And we already have a jack of all trades (NCASE M1)! Besides, now its pricier than M1 but cost can go down, using the same thickness of NCASE panel...
Thinner panels doesn't make the product cheaper. For these manually made cases, the cost is not the material, it's the labor / process, and anodizing.
Many anodizing shops in Asia are closed due to new environmental regulation, the end result is that we have gotten quotes where anodizing is half of the cost of the case.
