Absolutely true. For the propeller heads, there are certainly a lot of possibilities with off-the-shelf hardware. For people that 'just want it to work' without hunting down software, compiling, etc., NAS boxes on the market (doesn't matter which vendors' box; whatever fits their need) represents a more expedient solution.seems like a nice enough nas box, but quite honestly there are half a dozen others out there performing the same tasks. that was one heck of an expensive nas box though. i slapped together an old computer in a new case, an unused antec earthwatts 380 psu and threw on whs. bought 4 new 500gb hard drives @ 79.99. i can either swap out my drives for larger ones without a total redo, or i can add more drives with sata2 cards if i run out of sata2 ports. the antec 300 case i have has room for 4 more drives if i ever want them and cooling will never be an issure either. whs has way more features but i basically use it as a huge nas box. my main reason for going this way was ease of expandibility. just my 2 cents.
