With Schuko plug this ethernet controlled power strip is pretty nice

To be honest, if you want a cheap and scalable solution with good
electrical isolation, the solution I've seen quite often is to buy
wirelessly controllable power sockets (pack of 4 retails for ~15 EUR in
Germany). Wire up the power socket remote control with a raspberry pi
and you're done.

For serial ports, I just hooked up a bunch of USB-serial adapters to a
Raspberry Pi. Then again, this solution is probably unusable for
multi-user environments.

I use controllable APC rack outlet for this purpose, they cost almost
nothing, like <5$/socket for used APC AP7957 from ebay.
