That's right, if the hallmark were exclusively "the layout", then there are a lot of different T1s on the market, as all these cases use the same layout.
The hallmark of the T1 is, apart from being an SFF case, its image. The first impression one has about this case is its purity, the beauty of the design.
Some, like me, have been waiting more than a year for this case. Obviously we want a unique product to come out, and we don't mind waiting an extra month, for example, or paying extra 20€. The front panel is fundamental, it's part of the T1's hallmark. It is a product for those who know how to appreciate it in its entirety!
That said, I strongly vote for the "TwoTone" panel front, but, if the new conceptual panel design comes out ready, I'll be happy too.
