iBook G3 restoration

Yes I know I have restored it quite a bit, but now the hard drive has failed again and I need to replace it. I am also attempting to install Ubuntu 12.10 or 12.04. So pretty soon I will get a new hard drive and post some pictures. Once Ubuntu is installed I am going to start looking for three pieces of software. Minetest for ubuntu 12.10 or 12.04, OpenJDK for ubuntu 12.10 or 12.04, and DOSBox for ubuntu 12.10 or 12.04. Then I will install those and try and run some server type things. My main use for this computer after I restore it again will probably be a server for minecraft and minetest that I can bring with me to other places easier than a desktop.
