Poosible HTPC???

Hi all, I am new here and I hope I am not being too forward asking for help on my first post!

I am looking to buy a small PC to run XBMC on linux. I will be using a 2TB HDD loaded with FLAC flies, and another one with movies of varying formats. I have seen the following PC which has optical S/PDIF which is something I will need.

So, the question is will this work OK? Many thanks in advance for any advice.
