Since you're considering this so that you can run Cubase, you might want to find out if 1GHZ is absolutely required, or just a recommended specification. Have you tried installing and running Cubase on the 800MHZ machine? It may be that it does work on 800MHZ, just slightly slower, and who knows, you may find the speed acceptable. A 1GHZ G4 is really not substantially faster than an 800MHZ G4, and maxing out the RAM and making sure you're running Tiger instead of Leopard (Tiger is more resource efficient) would probably give at least an equivalent boost. Again, although most of the parts match and it is possible, I'd just hesitate to recommend it due to the cost and effort involved. But if you've done this kind of thing before, can get a 1GHZ board cheap, and 1GHZ really is the magic number that makes Cubase work, then hey, go for it!
