I am undertaking a project of that sort myself, though using a 64 bit windows platform. My focus will be on the computers performance as well as isolation, noise, emf/rmf insulation, as well as an internal (better than external) solid state dard drive (a few, probably). I am considering enclosures for an external power supply and interface for this PC, as well as those super silent PC cases (google them) further isolating it from noise. Kicking around mini stillpoint risers for mother board, etc, but could get pricey. not sure how crazy i want to get but right now, leaning towards it. there are also "silent" power supplies and an assortment of stuff to build an ultra quiet puter. I am already using an ESI Juli@ and the only change I would make is to mod it.
