Personaly I dont like all those acrylic cases for couple of reasons:
A. No matter how good you are at "hiding" your cables using cable managment technichues, this case is completley transparent, thus you'll always see the mass of cables where ever they are
B. Its plastic made...... NO TO PLASTIC! theres a reason people dont make cases [regular ones] from plastic although its much cheaper [theres also lots of reasons its cheaper]
C. Well, I just don't like the complete transpert kind of look.... it just catchs as an odd thing to my eye, but thats a personal thing IMO.
P.S. I'm not femiliar with many VGA Coolers but for as much as I know that Zalman VF900 supposed to be the top-of-the-art cooler for now, thats as far as I can recall.
