What to do, if i want to make my own youtube-like website?

I don't have any experience in building a server for streaming and also make an application for streaming. I can make an "ordinary" web, but for streaming i don't have any experience.
I read in some web that i need flash media server, video encoder, and other stuff.

For the hardware i'm thinking about building my own and the most crucial is the HD, because there will be a lot of read from that HD.

Can somebody tell me what do i need (software and hardware, file format) and maybe can point me to some tutorial?

Thanks,
Benji
