Physically it looks like the H50 can accommodate a standard motherboard in micro ATX form factor. You may have some trouble with the IO shield. But the PSU is the thing that worries me. If it's Lenovo's PSU it has a high chance it uses the non-standard 14 pin motherboard connector compared to the 20 or 24 pin connectors.There are adapters from 14 to 24 pin cable but i can't recommend them.
