MacBook Pro or Mac Mini as music server


Currently have apple extreme server. Also using the Olive Media Olive 4HD and Olive 2.
Thinking of adding either the latest Macbook pro or the mac mini as a music server for my cd collection.
Which of the two would be better suited to my task ?
I'm leaning towards the macbook pro 13" with 2.3 GHZ but then at almost half the price the Macbook min 2.4 is a steel but i wouldhave to add keyboard, a monitor and a mouse so cost would be close to the macbook pro.
Anything else am missing here ?
For the Dac, i plan to use either an I-Nova or a Bel canto designs dac 2.5. An esoteric D-07 is also not far fetch.
Would greatly appreciate some advice as i'm just starting out on this hobby (computer audio) just now.
Thanks guys-

Your dealer might be thinking about the simplicity of an all-in-one computer, but you have to consider whether you really want a full-sized screen in your audio rack? The Mini is tiny in comparison and can run without a monitor. You'll need one to set it up, but it can run headless after that for everyday use. The "Remote" app on an iphone or itouch gives you full control of iTunes. Or, if you have a laptop, you can connect to it via Screen Sharing (VNC) using a web browser on a Mac; or TightVNC, UltraVNC or RealVNC if you're on Windows. The Mini is an amazing little device.

As a side note, if you have a flat panel tv in your audio room, you can connect the Mini to it and stream movies from Netflix, Hulu, etc. It adds an extra value to the situation if you've ever wanted that functionality.
thanks for all the help replies! mac Mini might be it...
I'm giving it some serious thoughts.
I use a 5 year old MacBook for my server....have used the Mini as well, could detect no difference in sound quality and I'm not comfortable with "headless" operation.
Which monitor do you guys use with the Mac mini? I just need 15inches or 13". Any specific output the monitor have to be? Does monitor have to have USB?
Btw, might be very worth looking at a Mac2Music modified Mini, if it's in your budget.
