Thanks guys for all your input.
mgb: in fact, ham radio is not dying as fast as I'd tought where I live. Every winter, the local club is offering courses every saturday to get the basic license, and each year, we have around 15 to 20 students. What people don't realise is that when an emergency or a natural disaster strikes, the 2 first things that goes down with it are internet and cell phones. Also, a lot of the technologies that we are using now in our lives were experimented by ham radio operators. Still a lot of fun. Also, when I mentionned a pub table, I was indeed referring to a tall one with a 2 feet radius. Because of the size of the Titan unit I have, I'd have to go for a square 28", since a round 24" would be tight or a little short.
nitrogen_widget: Our attic is not suitable to have a living space in it (hope I said that right, since my native language is french). The house only has a main floor and a basement.
DeLuSioNal29: Nice find, I really like that ! Very neat indeed

I'll have to check wit Rick if he has plans for that kind of base for his cabs.
Generic Eric: Wall mounting could indeed be an option also. I'd have to find a shelf that I can hook solidly on the wall to support the weight of the cabinet.
Lots of thinking in perspective... Thanks again guys !
