I don't know what your budget is, but I found that the ASRock E3C226D2I Mini ITX "Server Motherboard" fit my needs well. Being an LGA 1150 board, it seems to support the i7-4770k CPU you mentioned and is about $100 more than your comparable setup.
It has 2 USB 3.0 ports, supports up to 16GiB of RAM, and has 6 SATA 6Gb/s ports, so I think it would also work well for a workstation board, if you added a video/audio card -- HDMI out is the only glaring omission for a workstation.
I'm using it in my FreeNAS fileserver and have been happy with it.
