I was specifically talking about wall-warts which are PSU integrated into the plug, not inline PSU, which feeds a monitor or laptop. As it is clear from the picture a wall-wart doesn’t take any more space than a mains plug.

Then, you also have to account for the excess cordage left over, and then you got a rat's nest like mine. Cables: Argh!
Linears are cool and I use custom open cage PS for Vdc (19V, 12V, 5Vdc) needs in the main audio room. which get routed thru some serious EMI filtering.
