I wouldn't recommend this, but if you wait patiently untill the daryna release you can install:
1) Daryna XFCE Edition- Uses the XFCE Desktop Environment. Needs about as much HD space (a bit less) then the normal edition, but is faster. Does include extras like Compiz Fusion, and all mintapps and codecs.
2) Daryna MiniCd Edition- Uses a stripped down GNOME. Fits on a 350mb mini cd, and doesnt take up much space on the hard drive. No extras, but all the minty stuff (apps and codecs). Is pretty darn fast for gnome.
