I'm recycling a leftover Dell Optiplex computer and it can only accomodate 4 drives. I'm thinking of using RAID 10 - would it be OK stability-wise if I put a small 80GB partition to store the OS? Thoughts? This will need to run as a file server as well as HTPC, it will be used for watching TVs, movies, blah blah blah. I think WHS does a similar thing just wanted to make sure. Thanks.
