I’m looking at building a cluster and I know there are different types. I haven’t fully decided on what I would be using it for.

Well, I have 4 computers about 3 or 4 years old and all have i5 processing with 8 gigs ram in each. I am not sure what size hard drives I want in them. I am looking at doing animations making my own small video movie like and then post on my blog. Even thought of other uses as well.

Would anyone have an idea what type of cluster I should go with. Thanks
