What size is my motherboard?

[CrazyMatt]

My motherboard is an Alienware 0PGRP5 motherboard for the Intel Haswell chipset. I was wondering which ATX (if it is ATX) size it is. Thanks in advance!

Edit: incorrect spelling

If this looks like your motherboard, it is a mITX: http://www.ascendtech.us/mmImages/b_0/PGRP5-03.jpg
If this is your PC, it doesn't look like it will fit even a mATX: http://cdn.overclock.net/c/c3/c37d0159_2012-02-01_16-42-36-1024_verge_super_wide.jpeg
