What do people think about this as a solution to the noisy G4s?

It's $900 plus shipping. I usually say, spend a little more and get what you really want (i.e. a new quiet G5 which would not only be an upgrade in noise, but obviously a better computer too.) However, a new G5 starts at $1500. So, assuming shipping is around $100, that's still $500 more I'd be spending to upgrade.

On top of that I don't believe Digi001s are compatible with G5s correct? So essentially I'd be looking at an entire new set up (which would be my preference if I had the cash...but I don't) just to accomodate a new computer.

So, is the cabinet worth it for an extended short term solution? $900 to improve the noise and keep my current set up. Or, put up with the noise and put that $900 toward the new dream set up which probably wouldn't happen for a while - and when it does, I'll probably have no use for the cabinet with a new quiet computer. Any suggestions?

Thanks,
