Is this BTX?

[gprime99]

I have a Dell 5150 and as far as i can tell its BTX but i have never seen anything BTX so if anyone could confirm its BTX'ness would help me out.My two hard drives go into that empty space in the bottom left corner, and the heat sink gets air from that big fan inside the black plastic beside the CPU.

Ya i needed to get a better PSU then the one Dell had in it. With my video card, sound card w/ front bay, and 2 HDD the one they had in it didnt give me enough power so i figured might aswell get something nice.
