PowerPC removal?

[whywhyhk]

I am sure stupid...... I downloaded monolingual and in the "Architectures" tab and there are 10 things to delete. ARM, PowerPC, PowerPC G3, PowerPC G4, PowerPC G4+, PowerPC G5, PowerPC 64-bit, PowerPC G5 64-bit, Intel and finally, Intel 64-bit. my current architecture is Intel 64-bit, and I'm wondering if I should delete the rest. and for some extra points, what is this supposed to be?

It's ok to remove the PowerPC architectures, but leave all the Intel architectures.
