You sound very enthusiastic which is highly commendable,
and understandable on getting your 1st PPC G4.
However I advise that you don't '
run before you can walk'. Give some serious thoughts to exactly what you need from a G4, what are your expectations, how much you wish to spend, and will that particular sum of money be cost-effective? If it were me the top 10 priorities would be:
i) Give the G4 a much needed internal clean.
ii) Ensure that you have adequate RAM
for the tasks you have in mind.
iii) Ensure the battery is providing a healthy 3.6V. Otherwise change it (after having cleaned the battery terminals).
iv) Check the optical drive for correct functioning. If defective clean the internal laser, and/or replace the optical drive for a known serviceable unit.
v) Prepare the 120Gb SSD with OS Tiger or Leopard, and install using a suitable IDE/SATA adapter.
vi) Read
THIS thread thoroughly and optimise your OS.
vii) Choose and optimise your browser. TenFourFox and Webkit are the popular choices but it's good policy to have several browsers for different jobs.
viii) Install a mechanical HD for data storage - 500Gb should be more than adequate for most users.
ix) If you intend to watch video content, installation of CorePlayer is a must.
x) Imho forget overclocking the CPU. But before giving the G4 too much extended running time, repaste the CPU.
Please provide feed back of how things progress.
