I'm just wondering where I have to put the reference node in this circuit when doing nodal analysis.

You can use any node you like to be the reference, but there will probably a certain convenience if you choose the bottom right node.

If I chose the corner to the left of the 2400ohm resistor that wouldn't work would it?

That would work, but I would slide the 2400 ohm resistor clockwise around the left hand loop and absorb it into the 3600 ohm resistor, replacing the 3600 ohm resistor with a 6000 o0hm resistor, and deleting the 2400 ohm resistor. Then the bottom node makes the most sense to use for the reference node.

You can use any node by using KVL and KCL rules.
You would probably come up with two simultaneous equations which I would prefer using some math software tools or advanced calculator to solve the equations.
