do I buy this G4?

[ptm at temple.edu]

Hi,

I am making a video film for a graduate project (a very large 
project) and I found someone selling a G4 for $825.  It 
sounds good but I'm not that savy, can you tell me if it's 
worth it.  Here's the specs:

1.25GB RAM
3X80 GB hard drives
400MHZ cpu
ATI Radeon 8500 Graphics card
cd/dvd rom
zip 100 drive
dual boot OS 9.2.2/10.2.8 intalled

That's what I know and I would really appreciate any feedback.

Best,  Paul
