These are larger in size than the laptops but smaller than a regular PC. The plus is you can install the highest quality drives, soundcards, DVDs/RW and so on available in the market today. The shuttle can be purchased with liquid cooling and is very, very, very, very....quiet!!!!

I just thought I would point this out for those who have to much money.
