I was wondering what sort of processor, motherboard and power supply should I get, I'd rather prioritise temperature and noise reduction over speed, I need it to run extremely silently, unfortunately I don't know where to start when looking for cooling solutions that'll help me out with this, ideally I'd like it to be silent enough so that I'd have to strain to hear it in my room, but as long as I can sleep through it that's fine.
Could someone offer some suggestions?
