Maybe this is just me, but I tried to make RH 8.0 as small as possible. I went throught the "custom install" and only selected a few packaes. I then went into the individual item seletion for each package and started removing things I didn't want. I ended up requireing over 1.6 Gbytes?!?! So, I guess you're looking at a couple Gigs min using RH 8. I probably I did something very wrong. But back to your question, I ended up giving RH 10 Gigs. It's mostly a workstation with an mp3 collection hogging up the HD. I'm running out of space now.
