The PS3 would have been ideal, and is in fact used in at least one parallel computing installation running Linux, but despite having hyped the ability to run alternative operating systems early on, Sony recently pushed out an update that killed the feature. There's some background info in the Wikipedia entry on OtherOS. It can still be done, but you need to be careful not to apply the problematic patches.
The same is true for the XBox 360: you can install Linux, but doing so involves installing custom firmware and probably voids your warranty, and Microsoft is actively patching the 360 to try to prevent this sort of modification. There is some good background in the XBox-Linux wiki.
If I was forced to choose between PS3 and XBox 360 for running Linux, I would choose the PS3, because there seems to have been more work done in this area.
