How do I connect to xserve A1246

Hope you can help. I'm trying to recover files from a server. It's an Xserve A1246. I know nothing about this product and it's to be sold at auction, but I need to recover very valuable sound and audio files first.

What kit, cables etc. do I need to connect, find my files and recover them? My guess is that there will be about 150GB of files. Do I just need a friend with an Apple laptop and a suitable data storage device?

I've never used MAC kit before so please assume I know nothing!

Many thanks
