pc vs mac, eac vs itunes

Multi part question: (1) Thinking of going to a musicserver rather than a wall full of cds. I have not been a mac user and would lean toward a pc based system. However, I have not completely closed off the mac option. Main concern is not degrading or changing the data. I have heard that EAC is the best option to insure this and I am wondering if the mac options will ensure the same integrity. I am not concerned with cost of external drives, my plan is to store on a number of external drives and make backups to a spare set of external drives. Looking for feedback on comparison of EAC with a mac option (or is it possible to use EAC with a mac?). (2) Goal is to be able to access everything from sitting on the couch. Any suggestions - both pc and mac based - would be appreciated.
