If it's stuff you don't use often, or use sequentially, such as  
videos, cd/dvd software images, etc, you may consider USB drives. Be  
aware that using the NFS kernel server and USB disk drives causes  
kernel panics, lost data, etc. You can avoid the problem using samba  
shares or the user space NFS server.

The user space NFS server is not compatible with some things, like  
RSYNC (missing function support), JDownloader (I/O on download  
directory) and the latest version of Ubuntu 11.04's gnome GUI (I/O  
error on home directory full "eye candy" turned on). With it turned  
off, it works.

Between Kravitz, Bug and Office Depot, they occasionaly have "disk  
wars" where they sell USB external disks very cheaply.
