Windows 7: offline share server

Hey guys, I have been wanting to create a massive offline storage space, something that is connected to a home network where all the devices connected to that network could access those files. Mainly I would like to accomplish this so I can back up all my movies onto my computer so that I can access them from all the devices in my house such as my home desktop, laptop, and ps3 creating a much more easier flowing home entertainment system. What are the best options to do this, as i would like to be able to use multiple 1tb hard drives. I would like to start with 4tb of space and expand from their as I have a lot of information plus well over 500 movies that i would like to upload.I was thinking of doing it all from my home desktop, but that limits how many hard drive i can have due to lack of sata ports. So let me know what you guys think the best way to do this would be.

Sure, all you need to do is share the drive. Right-click on it in My Computer, select Properties. In the Sharing tab, select Advanced Sharing and give everyone Full Control (or whatever you want).

Hmmm yea i know that i could do it that way,but i was wondering if their is a different way then using my desktop because it has a limited number of sata ports on which i could put harddrives.

P.S If you google it, you'll find a lot of information, cheep and expensive... start with above sites, and continue from there, and of course hang around here, there are a lot of power users here, and their experience counts ( a lot)
cheers

Thanks so much, I did Google, (I always try to Google extensively before asking) But i was not exactly finding exactly what i was looking for as I want to be able to add 5-10 Terabytes of space. I'll try your links and I'll see what I get, thank you.

*EDIT*
Link 1 is 99.9% of what I am looking for, thanks, I guess I will have to deal with the 4 sata port limit xD o well. Thanks guys for your time.
