He has repeated avoided addressing or countering this claim, which I think is a pretty straightforward admission that it's true. Should he address it directly, it would be totally indefensible, and clearly the best tact in this situation is to avoid addressing it. I think everyone here knows exactly what the case is - a clone of what is by most accounts the most desirable desktop computer on the market.
That said, to me, the quality and attention to detail do look significantly better than pretty much any other PC case on the market. And the aesthetics, while they are a compromised and blatant copy of an Apple product, are still a step above the vast majority of the largely stagnant and unimaginative PC market. Which says a lot about the gap between Apple's designs and the PC industry.
That is because they do not have to rely on external video connectivity, one of the benefits of a high quality integrated "non-upgradeable" design. The plastic Dell UP2715K 27" 5K monitor sells for $1600 and lists for $2200, while Apple lists a CNC'd and laser cut aluminum 27" 5K display of far higher physical build quality including a complete computer for only $1800. These sorts of comparisons and details are exactly why many Apple customers feel many Apple products are an excellent value. It really is a shame none of the major players in the PC market choose to compete with high quality products like this, but it ultimately speaks to the values of their customer base.
To be fair, the mesh on top is only necessary because of the compromised, off the shelf fan. But it does have nice aesthetics. Out of curiosity did you consider using a bottom mounted fan to isolate it from the noise (in either push or pull config), dual fans at top or bottom, or even going with a larger radial or centrifugal fan? It seems to me this thing is going to be loud - 30 dB is a lot for something sitting a few feet from you. My projector puts out 26 dB about 6 feet away from me and I hear it over movies and it drives me nuts. Apple clearly prioritized noise volume when designing the 12 dB (at idle) and 16 dB (at full load) custom centrifugal fan on the Mac Pro.
It does remind me in some ways of the Hoojum Cubit ITX case that I used to lust over, it doesn't seem like they ever got too much traction though.
Can we just take a pause from patting our visionary selves on the back and put this in perspective. You're making a (admittedly, very nice), but blatant copy of an Apple product, and marketing here on an Apple oriented forum. It does rub me the wrong way that you do this, after making a dig at Apple for being a "fruity" company, which is not only in really poor taste considering that dig is based on a gay slur - and it's 2016 - but also the hypocrisy that you take that dig in the process of marketing the closest you could come to a carbon copy of an Apple product that uses off the shelf (and compromised) PC components. That is right out of Samsung's playbook, and frankly to me seems like the low road in capitalism. I'd have a lot more respect for you if you just owned it, acknowledged it, and didn't take digs at who you're copying - it's tacky.
You clearly have some design talent, attention to detail, willingness to put time, effort and energy into making something high quality. And the PC world really would benefit from some truly top notch, high quality chassis designs, perhaps optimized around specific components, where the form truly follows the function. I think you could do it, and I'd love to see the results because I think they'd probably be pretty nice. With all that aluminum mass and CNC'ing you could come up with some impressive heatsinking, perhaps integrated thermo-electric heat piping, etc and really do something unique and lust-worthy.
