I mean, it is what it is. Do some new people get scared off from time to time? Yes. But It’s usually because of a concept or idea, not simply because they’re new.
Sometimes it's because that concept or idea, while perfectly sound, does not meet the approval of a few core members.
When I first joined, I got absolutely lambasted for not wanting to buy a particular piece of gear that I didn't need.
The piece of gear did not even address the question that I had originally asked.
I don't want to bring up the name of main offender, but most can probably guess who it was. Seems he makes a habit of it, so much so in fact that there is an associated catch phrase.
Anyway, I realize that keyboard warriors are often compensating for real life inadequacies, but I could see how such behavior might scare away someone who just came here to learn about this hobby.
You yourself were part of it. When I hit back just as hard (and then some) you implied that if I was not willing to tolerate his attempt to bully me that I would not be welcome on the forum.
We have since exchanged pleasantries elsewhere on the forum, and you seem like a decent guy with excellent knowledge of the hobby and a good sense of humor.
I do however think that if you leapt to anyone's defense on that occasion, it should have been the new guy, not the guy who is routinely an ---uvula--- to new members.
To the OP, if you're still here...
I totally get that you want to be considerate to your wife.
What we see as a really cool arcade machine, some wives may see as an ugly monstrosity.
My wife was not too thrilled with the idea to begin with (full-size upright that lives in the living room) but once she discovered Metal Slug and Ghosts 'n Goblins, she actually uses it more than I do now.
If that's not on the cards, then I think your wall mounted cab is a good compromise.
I do think the idea of a pedestal is a good one though.
Alternatively, why don't you try a bar stick as your first project?
It's a control panel containing a computer that you hook up to your TV and use like a pedestal, but can easily be put away when you're not using it.
If you do decide to build a cab afterwards, a bar stick is still awesome to have because it's portable enough to take to parties etc.
