I have a PowerMac G4 MDD with these specs -Dual 867MHz -2GB RAM -3 x IDE HDD etc. I have set up file sharing and networking with other PC's and Mac's in my home network. So I will use this as a file server. I would like to upgrade to SATA, and would like to know if the following will be compatible with my PowerMac SATA Card http://www.amazon.co.uk/SATA-PCI-int-ports-VT6421a/dp/B000LS4LXS/ref=cm_cr_pr_product_top Power Adapter http://www.amazon.co.uk/StarTech-co...-Cable/dp/B0002GRUV4/ref=cm_cr_pr_product_top Hard Drive (may buy 2 of these) http://www.amazon.co.uk/Western-Dig...1_4?s=computers&ie=UTF8&qid=1296321261&sr=1-4 Please let me know if these items will all work and be recognized by my PowerMac. Also, if I only purchase 1 hard drive, can I add another for a RAID 1 setup in the future ? (mirroring) via software. Or do I have to buy 2 from the start to create a RAID 1 setup ?
