No. I even compile TenFourFox in 32-bit mode for G5s because it has Carbon
dependencies.

G5s as a whole can be cantankerous and difficult to repair, but well treated
they can last for a long time. It helps to buy the right one, though.

Personally, I believe the only two worth owning are the dual 2.3, because it
is the fastest air-cooled G5, or the quad 2.5, because it is the fastest
Power Mac ever and its liquid cooling system is more reliable than previous
machines. G5s slower than this are not significantly faster than the G4s they
replaced and have more headaches, and the other G5s have various higher
than average component failure rates (usually power supply or LCS).

In your case, you may need to consider the dual 2.7 because it will still
accept your PCI cards; the quad 2.5 will only handle PCIe. However, the dual
2.7 is actually not as fast as the quad (not only cores, but bigger caches),
and it has a higher LCS failure rate.

I own a quad, and it is a solid machine (and has been for over six years),
but it is power hungry and can be noisy. Still, it runs my Power Mac apps
like nothing else, and my legacy hardware was all external, so the PCIe slots
are now filled with extension cards instead. And interestingly my MDD has
failed more times than the G5 (the MDD has blown through two power supplies
in its lifetime, while the G5 has never needed any significant maintenance
other than cleaning). But the MDD will be cheaper to buy, a bit quieter and
less expensive to run and maintain, so given that you have a need to keep
your old PCI cards, an MDD may actually be a better option for you if you
don't need the "fastest Mac ever."

My Dual 2.7 is a very reliable machine since I installed a Panasonic LCS three years ago, I had to repair the stock Delphi twice.
