Great! Where did you get that box for your alarm ?

It's a regular electrical box I've bought in electrical shop.

First of all I want to thank you guys for your comments. I really appreciate it.
I spent on this project about 25 USD:
* electrical panel box - $3
* 4x4 Matrix keypad - $4
* 1602 LCD - $4
* ATmega328p - $4
* prototype board, buzzer, relay, 74LS164, etc. - ~$10
