I hope you like puzzles, because the photos you see here on Amazon are the only documentation you get to assemble this. First, peal the protective coating from either side of the acrylic. Attaching the four legs is obvious and trivial. I mounted the power supply next but, in doing so, covered up one of the holes to mount a standoff of the motherboard. Not a big deal -- I just attached a standoff to the underside of the motherboard in that position to provide stability.The power supply mounting hardware comes with two 'Z' shaped brackets. You'll use one of them. It attaches to the acrylic by using your choice of any of the elongated slats that are milled -- whichever works best for you.The expansion card mounting hardware is probably the trickiest part to figure out, but the photos pretty much tell the story.One complaint I have is that the back-left leg mount blocks using the left-most expansion slot on my motherboard. I bent the bottom of the card mount to get around this.Good luck
