Im in the process of gathering parts for my future nas build. I know very little at this stage. I see a limited time deal (in a few hours) of Lsi9750-8i w/ BBU deal for about $64usd. 

I plan to have 4+ bay. I am thinking i can get used cheap motherboard with 4 ports like b75m, cheap CPU, then it all fits together. Is this ldea good?

Or get a 8 sata good motherboard? but I plan to keep the budget small for the nas.

In terms of upgrade path, stability and others... So what should i do??

I have yet to decide which nas to use, but Im more incline to unraid for now.


Thanks alot

In my brief googling I was unable to determine whether or not that card can be properly set up to support unraid. I rather doubt it, so that particular card probably is not a good candidate if you are serious about unraid. Unraid really works best with a plain non-RAID drive controller, fancy RAID levels are not used, and can interfere with unraid's ability to manage the drives.

What about other nas os? If i go other routes it may become useful? or a good deal?

This is a forum for unraid. I don't run any other NAS, so I have no idea. You would need to check with the other candidates to see about their compatibility.

unRAID works well with an LSI SAS9201-8i, which can be had for <$50 USD.

 

That's cheaper and known to work with unRAID.

Is a BBU needed for any reason?

The only time you need a BBU is if the card has memory on it to provide a read/write cache.  I have my doubts that a cache would give you much of performance boost in unRAID.  It would help if you were using hardware raid instead of unRAID.  I prefer unRAID I've lost too much data on hardware raid cards when more than my parity protection limit of drives have been dropped by the controller causing all data on the array to be lost.  That cannot happen on unRAID.  In my mind it (unRAID) is the perfect solution for a home media server.
