The following chipsets are compatible with the 2400k. This is an older CPU and they do not makes these boards anymore so you will need to look on the second hand market. I would try ebay.
Intel B65 Express Intel Q65 Express
Intel B75 Express Intel Q67 Express
Intel C206 Intel Q75 Express
Intel C216 Intel Q77 Express
Intel H61 Express Intel Z68 Express
Intel H67 Express Intel Z75 Express
Intel H77 Express Intel Z77 Express
Intel P67 Express
I would look for the H61, H67, or Z68. The Z68 mobo will be your best option as it supports overclocking and you have an unlocked chip. But the Z68 will be more expensive.
Here is an H67 board that is not a bad price and will work with your CPU. Shop around, you may find them cheaper.
