It's a 1.83Ghz Intel with just 512MB memory with a 70GB HDD and Superdrive. Also running a 330GB external HDD.
Two years ago it was bought when I started running a Media qualification (BTEC for anyone interested).
Originally we got it for students to use with Imovie. Using it with FC has just been a recent experiment, as we've started putting together some school promotion videos - hence the newer cameras (which, typically, I had little say on - to be honest I would have chosen different, as my needs are different for teaching).
My plan (although whether my superiors agree is another thing) is to buy a newer machine to run FC on for bigger projects. I'm also going to be replacing my own (old) IMac later in the year, and intend to do some work on this.
Anyway, enough whingeing about the lack of funding for Secondary education in the UK...
How does it manage?
As a guide, it takes around 2.5*real time, e.g. 1 minute of footage will take 2.5 min to import.
Converting/exporting takes a while as well. Off hand I can't remember - I'll put up some info for anyone interested when I next do it.
Overall I would say it just about does OK. I've changed the frame rate on playback to avoid dropping frames, but I must say that otherwise, it is worth the effort.
