Idea is to install some lightweight Linux distro, and Renoise as user session ie after log-in it goes straight to Renoise.
It must be silent, no fans, no buzz. Essentially becoming like a hardware sequencer. I do not use too many samples, synths or efx - as long as it’s somewhat similar to Lenovo T460 era laptops it’s all good.
Used, and not too expensive ofc 
Cheers, Thanks!
