Unless you removed it for the pics it looks like there is no CPU, you'll need at least an A3630 or A3640 to get it up an running, better a proper accelerator like a Cyberstorm/WarpEngine if you can find one.
Without more pics I can't say if it's complete but at least you have the SCSI board and Video/Sound Board.
Zorro slots look empty, they are for upgrades such as Video, 16bit Sound, Lan, etc.
