Debian or Fedora

[Glenn at home]

I have a computer hooked to my network that I am planning on installing 
Linux onto.
It only has a 25 GB hard drive, and I want at least 20 GB for FTP files.
I have been thinking of trying Debian since it appears that it may take less 
disks to download.
I only want Linux right now for an FTP server.
Since I have not heard otherwise, I understand that Debian is not ready for 
prime time with speakup, so I guess I must go with Fedora, but that takes 3 
ISO's, unless I can get an FTP server going with only the first ISO.

Can someone advise me here?
Thanks.Glenn
