I have EG4 6000XPs in our mechanical room (much sound insulation) and am very happy, but for my separate 16x22 office, where I would hear fans, I have a Victron system with a SEPARATE, passively cooled SCC, because I don't want to hear fan noise. On the sunniest of days, silence! I use a small Multiplus for the inverter. You'll likely need multiple SCCs with this approach, and of course a separate inverter (maybe two), and it's going to cost more. But it's worth it.
Bottom line: If you can put the equipment in a separate area that prevents you from hearing it, an AIO is often great. But if you're forced to have equipment where you can hear it, I don't think you can beat separate components with passively cooled SCCs.
