Well I was bored so here. I just built a general-purpose studio package. There might be some holes or unneeded items, it just depends on the reasons for the studio.
In this system, you have the option of running the HD24 recorder remotely. Otherwise, it functions as the ADA converter for the computer, through the M-audio Lightbridge. The Yamaha mixer provides the front end, for up to 24 mics. All accessories needed are there I think. The mic selection is mostly general purpose mics that I think is a well-rounded group. No ribbons, because putting ribbon mics in the hands of younger students is, well, stupid (I don't let anyone handle mine, at all). I've included some software plug-ins but I'm not totally hip on them - I hardly use effects not in Sonar already.
There is some money left over to get random stuff or more accessories. You might just be able to squeeze some active PA speakers in there for live sound. You could also shave some money off by buying cables from a cheaper place, such as www.audiopile.net (this is where I get all my cables).
If the program wants to hire a consultant to run the build give them my number. It's on my website - www.oceanstarproductions.com. My equipment list is also available there.
Anyway, here is the shopping list from Sweetwater.com:
