Thanks for the info. Just one more question: There's a 1.67GHz Powerbook for sale, it's in mint condition and quite cheap.

Here are the specs: 1.67GHz PowerPC, 167MHz System Bus, 2GB DDR RAM, 1440*900 dıilt-in display, 128MB DDR ATI Radeon 9700.

What if I buy it; would it play 720p movies without those issues that we encounter in Mac mini G4's ?
