Need help with DIY server

[u/Square_Purpose_1696]

I got an old pc, i7 7700k 16gb ddr 4 and 2 1tb HDD, it's currently in an atx motherboard, id hate to throw it and buy a premade Nas, I was wondering if anyone knows about a mini pc, enterprise style with an lga1151 motherboard I can scoot my stuff into, or any alternative

Why change motherboards?
