Yea unfortunately that's normally the case as it depends on how much room you have to work with, what you want to do visually in certain angles. A lot of that's quite hard to visualize over words and even photos. If you are planning on mounting the powerbrick on the side/back of the table somewhere, you could try using the 3m mounting tape (double sided stuff of course). That adhesive is very strong. You could even fabricate rigid metal piping to fit your needs with the use of electrical elbow boxes and what not. But that's really a lot of work and custom work. Nothing off the shelf of course.
