I run SuSE 7.1 on a 1.2gb hdd. after the initial install i had about 8% of my hd left. Since then i have eliminated a lot of stuff (don't really need 6 text editors do i, or 2 or 3 cd players etc.) Have about 28% of the hd free now. So as long as you get rid of some of the stuff 1gb ought to work fine.
