That appears to be an external USB powered hard drive, with a additional video driver and video outputs. Most likely any computer that has a USB output should work with it. But you might ask LaCie, but I didn't see where you had to install any programing in the computer to transfer files to the unit. You could DL the PDF format manual from LaCie for more info: http://www.lacie.com/download/manual/silverscreen_en.pdf
EDIT: Here's one review from 2005: http://reviews.cnet.com/portable-video-players-pvps/lacie-silverscreen-40gb/4505-6499_...-31256889.html I see the price for the 40GB model direct from LaCie is about $80US.
