The Logic Off Topic list

Hi all,

I'm looking to buy a FW case for my western digital 120 GB disk,
to go with my new iBook G4.
I will be using the disk for audio with logic.
I will also be using a FW MOTU 828, so I guess the HD should have a 
link-thru FW-connection?

Are there any specific things I should take in account when buying such 
a case? Are there speed or compatibility issues?

Thanks!
