+1 for GPU additional fastening
As for the PSU, I never heard about silent flex PSU with proper efficiency. Maybe there is a solution for that somewhere, but I predict it will be something like a high power PSU with passive cooling option (for example 800W PSU for a 300W system and low fan ramp). The main problems with quiet flex PSUs are probably poor availability and lack of other options. It means, if you say that there is a manufacturer for quiet flex PSU, then can you mention one ot two more, so people would have options to choose from? There is nothing worst for a design than closing it for only one supplier for its parts. I really would like to see some tests of those silent flex power supplies, because i had contact with many of them, but none were at least as silent as standard sfx PSUs.
For small production run the price may be justified by a very small amount of manufactured units. With bigger production you should ask your subcontractors for better offers, so you could lower the final case price and get more buyers.
That is not fully true. Everything depends on where you are with your product (in time). At a place where you are with your case, to sell it at a certain price you have to justify it (clarify to you clients why this product is worth their money and why it is better then other similar products they can buy for the same amount). If not, you will not build a proper demand for your product.
Tbh I did not notice that this mesh is going to be permanent (only for prototype or something like that...). If you want it that way, then why you just not add some steel tapes on the sides and place a proper magnetic dust filters, like those from www.demcifilter.com?
Ok. High price in your case is justified by low production run. Got it. I thought there is something else (in your design) which generates high costs.
Please, do it! I invite you to participate in our project threads. All those questions were asked hundreds of times and you can find answers for them.
What is more, Sentry is a community project, so current version 2.0 is mostly redesigned by people who already bought previous version. We are talking about problems, possibilities, improvements, costs, prices, timelines all the time. I don't remember other case project in which feedback from people had such big influence on the final design and in which people knew so much about its manufacturing costs. Our daytime jobs are somewhere else so we are not scared to give answers.
I think you overreacted a little bit. If you felt attacked by my questions, I am sorry for that. That wasn't my point. In the world where something like 95% of pc cases production comes from China, you are making your cases in the USA like Josh used to, and I thought you might be a good source of proper information about real costs of production there. That's why i asked those questions.
I think if you come to technical forums you should be prepared for such questions. If you find people complaining about something and you can't or don't want to defend your decisions properly, then you should stay on reddit. In forums like SFF or [H]ardForum we are talking about every aspects of design, including its improvements, flaws, manufacturing costs, etc. If people will see that you came here only to talk how good is your design, and you will not going to listen to them or give them answers why you did this and this in that way, or if you can make this and this better or cheaper, then they will think that you are only making an advertisement of your product. You won't build a demand that way. Please also visit Sentry, A4-SFX, NFC, Ghost threads and check if there is no complains about costs and prices. I can assure you are not the only one who have to face those questions and with prices $200+ there is way more complaints than you have to deal with
