RCAs are "OK", but I personally wouldn't go further than that. I have a pair on my mixer and on each of two speakers that are their primarily for connecting a laptop or a tablet, which are normally fine if not powered, otherwise there's the usual issue of hums and twitters. If I need them, in practice I usually feed into them the output of a Logitech Bluetooth audio module and connect via that.

I'm thinking more of live sound than studio here, so perhaps I'm being a bit harsh. Any board within the PC is potentially exposed to whatever supply and EMI issue there may be inside the box and/or coming out of the box on signal and ground wires. A DI box can often resolve things, but it's another box and another set of cables and connectors, probably another plug-top power supply (as for the Logitech) and so on.
