Mine is on a rack shelf in my 20 space rack. Means I have to run longer speaker cables to it and then back for the cab the head is sitting on, but keeps it out of the way and accessible.
I have my suhr RL and RLIR on top of the rack and when I reamp with them, I run them into a Racked up Marshall 8008 valvestate power amp.
But you asked about gigs, when I used my power station live, I used it as a load then into an IR loader. I do have a head that fits on top of the PS2, Mesa TA15, but most do not, so what @CarlF is doing looks like a great idea. to transport, look at a laptop bag, works pretty well.
