What type of motherboard does a Dell 560St have?

So I have a Dell slim tower computer that needs a bit of upgrading. I want to buy a new case, but not sure if there are any out there that are compatible. Could anyone please tell me if this motherboard on the computer is an ATX or micro ATX?What type of motherboard does a Dell 560St have?Intel G43 Express, your motherboard will fit fine into any standard mid-tower or full-tower case.What type of motherboard does a Dell 560St have?Judging by your PC size.
