After installing a new OS X system, the computer could stand for an upgrade in RAM
to at least 2GB of quality RAM, not cheap generic product, so it will run w/o issue...
Also, you may wish to be on the lookout online for an iLife application set on DVD for
the era of OS X you are to be installing. This provide iPhoto, iMovie, & GarageBand;
more commonly included applications similar to those which shipped in the original
bundle of applications. iLife '11 may be OK for use in the computer you have, and it
would be shipped from an online re-seller, on DVD media.
Some places online may sell the set of OS X 10.6.3 and iLife '11, perhaps iWork, too.
These would be 'retail DVD' and best price for Snow Leopard is Apple online. The
other items, iLife and iWorks, among other dated original Apple software may be
found by searching online. These would be on original DVD media.
A more recent browser may be Firefox from mozilla, as Safari is a bit dated, but was
included in the Snow Leopard system. Not sure if there was a later Safari available
after the one 10.6.8 included. After installing 10.6 on DVD, run Software Update in
the system, [or use link] to get 10.6.8 Combo update, install it & then run Software
Update again, to see what else may be out there. If you get the iLife or iWork apps
then repeat the Software Update to see what other parts may be free to update them.
Good luck & happy computing! 🙂
