Storage space is getting cheaper all the time, so there's not much reason to not use an external drive to store all of the media and control it with an iPod Touch. As long as iTunes is open and the Touch can access the home's network, it work great is easy to use and sounds as good as the codec allows. FLAC, AAC and the other lossless formats will work best and ofr dumping to the iPod itself, the format can be determined at that time. If it's not practical to run cabling from the computer to the audio system, the Aairport Express is a great tool and it's about $100, so that will replace about 1-1/2 hours of paid labor + parts. The big benefit is that it's portable.
