Sflack Linux doesn't require an extremely powerful system to run (though having one is quite nice :). It will run on systems as far back as the x86_64. Below is a list of minimum system requirements needed to install and run Sflack.

• amd64 processor
• 16MB RAM (32MB suggested)
• 100-500 megabytes of hard disk space for a minimal and around 3.5GB for full install
• CD-ROM
  

Additional hardware may be needed if you want to run the X Window System at a usable speed or if you want network capabilities.
