You’re good with a Pedaltrain Classic - they’re raised at the back with room to mount the power supplies underneath. I’ve got a Truetone CS12 mounted under mine.
I’ve had two Pedaltrain boards - a Classic and a Metro, they’ve both been perfect. Sturdy, not too heavy, robust soft bags.
Ta loves. Last question, will mounting two small 5 output powers supplies be an issue on a pedaltrain classic?
Edit: fuck it i'll deal with that later. Just ordered a Pedal Train 2 off a shop in Bournemouth via Reverb for £99.
