bigger, i gots a server case, the only differnce i can see is that its pehaps a tiny bit bigger than regular cases, mine measures 21" high, and 9" wide and 19" deep
Well you always want to make sure your case is cool. You don't need to get a server case, you can get a good thermaltake with good airflow and you'll be set.
Well, when i worked with the case, and saw it used in several builds, i was thouroughly disappointed with the build quality, esp. in the hinge and flap area.
Read around, the armor really isnt that great a computer case. Looks arent everything.
