I did configure the mini server with 250GB ssd and 750GB hdd option, 8GB ram. It puts the G5 dual 2.0 to shame in all matters.. not considering the expandability features of the latter of course. But the i7 quad is far more processor, and with the ssd waiting for my machine to do anything is a distant memory unless I'm downloading 1GB apps that still takes a few minutes.
As a photographer I feel that I made a very value wise decision, not needing any display but needing up to date performance from my apps.
I have no experience with FCX or FCP. But CS 5 and Aperture 3 are immediately responsive to my commands, Aperture 3 being the weak link imo.

I have yet to hear my mini's fans, positioned three feet in front of me at ear level.

I remember you saying that you were going this route a while back. How has this new setup performed compared to your last setup?
This is what I'm looking at right now. I do a good amount of work in Flash creating cartoons, short animation and some stuff in PS & Illustrator not to mention I'm thinking about getting Aperture 3 soon. I also have been doing a good amount of video for seminars on the weekends and the new FCPX is looking like an addition in the near future for me. My 17" MBP is showing it's age with the video editing (see my sig).
Can you give some real world feedback once you have a chance or send me a pm with some import/render times and file sizes if at all possible?
I'm in that same boat of questions right now too. I'm leaning toward the server because I'll max the Mini out with RAM & split the storage with the SSD & HDD configuration for the most bang for the buck.
To extend that question, has anyone used Motion or anything in conjunction with or other than FCPX on the new server and how has it worked thus far?
