I was wondering what you guys preference was to tkl case design? I've seen some different varitions, and some are pretty alike so I'm not sure if there is a difference. And it seems that some would be more efficient than others. Examples:
Firstly I present the TEK-80, this one has BIG bezels.

It seems to me that this would be kind of inefficient since you have to reach more to get to the actual keys themselves since some space at the bottom is reserved for a bezel. Also it looks bad in my opinion.
Next: Orion V2 tkl

This has thinner bezels, and even thinner gap between the function keys and the main keys. While this is more efficient as it makes the function keys easier to reach I think it doesn't look too good so thin.
Last: Mira

This one has a bigger gap between the function and main keys which I think looks better (at least I perceive it to be bigger I'm not 100% sure it is). Could someone tell me if these bezels at the top and bottom are the same size as the orion v2? I think I like this design the best aesthetically. Isn't this really just the most common design which most retail plastic tkl's have?
What do you guys like the best aesthetically? And concerning efficiency? Also, what other kustom do also have this mira design?
And lastly, what board is this?

It looks as if it has a similar spacing on the bezels as the mira.
