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-

I have tried both and the 2010 Mac Mini kills the Macbook pro. I have a 2010 Mach 2 Music mac mini and it is the best transport I have ever had especially with the Mach2 Music Modifications. I now have a Mac mini where the internal switching power supply has been removed and now runs on a battery. The battery is a huge improvement. It has come very close to my turntable. I cannot convey how deep and wide the soundstage has gotten,how perfect the tonal balance and did I mention the detail stuff I have never heard in the digital domain . I am very happy.

On the subject of monitors -- I'm just using an HP 13 inch VGA monitor that's at least a couple years old (I'm not completely sure because I bought it used at a pawn shop) --I got a dvi-to-vga adapter from Apple for the mini and plugged the monitor in. Apple's OS automatically recognized the monitor and offered up a variety of possible screen resolutions. I just fiddled with the different resolution options until I found one that I thought looked good. I had a spare wireless keyboard and mouse sitting around, so that was no expense -- I do keep the monitor in place all the time, althought it is often turned off -- I find it easier that way to deal with software upgrades and new music purchasing.
Mac mini and a used or refurbished ipad. That combination should cost less than the Macbook Pro and will allow you to run the mac mini headless. Rowmote, itunes remote and Wyse PocketCloud VNC (free edition) will allow you to control everything you need on the Mac Mini.
