I have finally got the computer up an running. I had to get a 160 gig hard disc from ebuyer.co.uk, but it now works as good as new. What is a pain is that I haven´t managed to save all of my files. My FreeNAS server is doing well and keeping backups of all of my important stuff, but I lost all of my videos and every save game I have ever made.
As we are quite strapped for cash at the moment (broke really) I could only afford a 160 gig disc. I suppose when we have more money I can get another drive of the same capacity and install SuSE onto it.
