That's the brand (Lenovo) the platform (Intel) and the chipset (H81) but is not the model. The model should be printed somewhere on the board. Usually along the top edge or down the middle somewhere.
Since this is obviously a prebuilt system motherboard, then it may have a proprietary front panel pin cluster on the motherboard that requires the wiring connector that came with the Lenovo case that it was originally installed in, or an adapter harness to connect a standard aftermarket case to that board. You may need to do a bit more investigating to find out, but it's not likely that it's the same. Knowing the board model, exactly, would be helpful.
You MIGHT also be able to get the board model by typing msinfo32 into any search or run box on the start menu, pressing enter, and then in the system information applet that opens look for the "baseboard product" or "baseboard model" in the right hand panel.
