Subject: case vs using if question

Hello all,
Nuby  question?
I need to parse the syntax on files based on a two charcter code such as 
PC which would return a value like this PC = Postcard  I have many many 
codes and Im very new to Ruby and not sure what the best way to do this 
is and performance considerations?  So would multiple if statements be a 
better ruby way then using case or does it mater?

example:
file name: d123456_PC_xxxxx.pdf

filename.split('_')[1]

case component
    when "PC":  puts "Postcard"
    when "DC": puts "Decal"
else
    puts "n/a"
end

or

or am i better using
if component == 'PC':     puts "Postcard"
 elsif component == 'DC':     puts "Decal"

....etc
