I'll leave to moderators to decide if the forum is right or wrong. However, this doesn't belong to the "market" section because I'm not offering any service yet.
Good luck mate. It's good to have more case suppliers, it actually makes it more healthier for the DIY builders in my opinion.
You might have a different take to the case design, service, approach, price, etc.
Also other suppliers may be out of stock and you can fill a void and vice versa.
I mean look at the 1073, gssl, u47, clone market, etc. we are filled with them and people continue to supply, design and buy them.
Competition keeps prices down and quality up in my opinion.
From my limited overview, there were only a few people supplying cases and people accepted poor quality, service, etc., now that the market has widened, people are not taking as much crap from it and it keeps suppliers on their toes.
