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 ?

Thank You all with those informative responses.

Suppose i go with a mac mini as Robert and others have suggested, and use my LCD TV as a monitor with wireless keyboard/mouse.
From my sitting location, the TV would be 10 feet away and the main audio system (DAC) about 15 feet the other direction so approx. 25 feet between the TV and Audio system.
Where would i position the mac mini?
I would need 2 USB cables (one to the TV one to the DAC). I would like to use the best quality/shortest USB cable to my DAC like a RSAD Poemia or better.
I want absolutely no compromise in sound quality.
Again, thanks for all your help!!!! Sly.

I would go with a PC.

Why?
1 - You can build it yourself to your specifications. Better power supplies for a music server make all the difference in the world.
2 - You can select your case and motherboard. With a PC, you have have insane expansion.
3 - I am not sure Exact Audio Copy (EAC) is MAC compatible. EAC is the best way to rip music from a CD.
4 - Foobar2000 - I am not sure if it is MAC compatible as well. Foobar2000 is the best way to play music on a computer. It even has an Apple Lossless plugin to play these (Apple Lossless) files.
5 - Empirical Audio's Offramp Turbo2 or 3 device for exporting the digital data off your computer - I do not think this is MAC compatible either.
6 - PC will most likely be less expensive

I have over 7 years of experience in computer music server playback. I will confess that I have never used a MAC for it. But because of the above reasons, I'd go with a PC.

iMac for me. I upgraded the memory and added an external 1TB hard drive. Toslink from the iMac to the Processor. Works great. iTunes is a breeze.
Ripping with iTunes does not compete with ripping with EAC.
Playback with iTunes does not compete with playback with Foobar2000.
