I am running it by intel-i3 and 256m RAM, with nvidia geforce 9300GE(a pc bought more than ten years ago orz) Zorin Lite 12.4 fits my drive quite smoothly. I find it great for that it looks like something rather modern while has a effiency just like XP. The built-in packages and drives also makes it easy to get start. Since the system is based on ubuntu, references are easy to get and the operations are familiar to most user.
