When this computer came out it was top of its class and very impressive. Now however it struggles to do most things apart from look amazing.
It runs on the old Power PC architecture and has a 400MHz processor, however, from a new install it is still quite swift at editing video with the supplied software. The 10gb hard drive is no where near sufficient for any serious video editing that you'd like to do. However it is upgradeable quite easily to something larger, say a 120gb one.
It has a slot loading dvd/cd player which looks quite cool but you're a bit stuck if a cd gets jammed or stuck inside, as there is no manual release like on tray loaders.
The graphics are acceptable for something this old but don't expect to play any recent, nay ANY games on this thing.
It performs office tasks mediocrely with a bit of grunting and noise from inside, and it freezes if you do to many things at once (e.g. work on a spreadsheet and a presentation at the same time) due to its 64mb of RAM.
Overall, if you're looking for a computer that's cheap and you can write the occasional letter on, this can be it, just don't expect to do much else on it.
