How about instead of mounting it to the wall, use a couple vertical tension rods from floor to ceiling and connect shelves to those? See this IKEA hack:
Oh, actually I see Johnny answered with a similar post. But while the link he gave works, the links at the site he gave (which detail the parts used) don't seem to be working for me.
Anyway, a quick look at IKEA's web site should give you some parts to use. Like these:

If it's just a small component like you mentioned, you might even make do with just one tension pole. No need for a shelf! To mount your device to the pole, you can do a number of things. First, you can buy one of those "O" rings and mount a small, lightweight shelf to it - maybe a thin piece of backer board or plastic from a clipboard or something. You just have to drill a hole into the shelf and attach it with a screw, two washers, and a nut. And then put your device on top of that.
But that may not be a perfect solution if the "O" ring can't handle the force or the shelf sags at a downward angle over time. Instead, you might want to just make your own custom plastic frame to hold your device. It's super easy. Just buy some some Insta Morph and shape it into whatever you want.
Insta Morph melts at 150 degrees F, and then you can shape it for a few minutes until it solidifies. It takes about an hour for it to become completely solid, and when it's like that, it's indistinguishable from any other hard plastic you've seen. Just have to watch the heat from the device, make sure it doesn't re-melt the plastic (it can be melted again and reused any number of times by the way)...
Oh and by the way, the idea of using vertical tension rods to make shelving is genius. It's easy to put together and take down. It's very customizable, allowing any shelf width and depth you want. It can be added onto later on if you want. And in my opinion, it looks very nice, clean and modern. You may not need the shelving for your purposes, but it doesn't hurt to have extra shelving!
