I love the look and feel of this case. Much like its bigger brother the TX 1050B, the TX640B has a thick outer shell which should stand up well to any abuse. The aesthetics of the case are simple, but should have no problem fitting into any environment.
The front panel features the same plastic construction of Antec's other cases to date, but the lack of a front door means your external drive bays are exposed, which isn't a problem in my eyes as I'm constantly switching out disks and fiddling with my system. The lack of a door also means there is one less moving part that can be broken.
