PC vs MAC laptop as music server


Hi All,
Looking for a laptop exclusively for surfing the web and use as a music server.
Will use for ripping CD's and downloading Hi Rez music files (HD Tracks etc..)
Would also use to sync to my IPOD 160gb and connect laptop to ARC DAC7 using USB cable. DAC7 connected to an all Reference ARC system.
Speakers are Verity Audio Parsifal.

Should I go PC or MAC ?

Sound wise the two are very close. A more appropriate question to ask is which type of HD should you use. SS HD wins hands down vs. traditional spinning HD.
