The One Hundred is a better deal and has a larger interior.
Also comes with 2 Two Cool exhaust fans.
I have a 430 and other then the 431 having Usb3.0 and some cosmetic changes it's not worth $60+.
I paid $40 for my 430 and like the 431 it only comes with one 120mm front intake.
The Antec offers superior cooling options.= 2x120mm front intake.(optional)
