I want to build a home multimedia centre to store all my movies and music. Currently I have about 400 movies and 80gigabyte of music. I want to build a pc with Raid; (probably raid 2). I know that I will have to change my hard drives every few years. It will be more like a home server and I will be connecting to it wirelessly also. Should have HDMI out and will be connected to the internet for remote access. Can you suggest an Operating System (don’t mind XP as it’s quite stable) and best mother board etc. I’ll also be adding movies and music quite regularly. This system will be running 24 7.
