2.5. Memory and Disk Space Requirements
You must have at least 32MB of memory and 110MB of hard disk
space. For a minimal console-based system (all standard packages),
250MB is required. If you want to install a reasonable amount of
software, including the X Window System, and some development programs
and libraries, you'll need at least 400MB. For a more or less complete
desktop system, you'll need a few gigabytes.
