The first step to constructing this cube case is to take a look at the instructions. These are included on 8.5x11” copy paper and include a full illustrated version of the page’s steps. These instructions label all their parts with numbers and correlate with the parts list on the first page. It is important to use the right parts for the assembly of the right pieces; otherwise you will probably not have a sturdy box. While doing a run through of the instructions, I did notice that the parts list did not match 100% to the labels on the parts baggies. Essentially the screws labeled for construction of the side panels were in reality a different (shorter) type of screw according to the baggies. I went through and tested all the parts and re-numbered them to match the instructions. It pays to do a run-through of installation before actually jumping in!
Step 1: Attach back I/O Frame to Back Panel
Step 2: Attach 5.25” Brackets on Underside of Motherboard Tray
Step 3: Attach Motherboard Tray to Back Panel
Step 4: Attach Rubber Feet to Bottom Panel
Step 5: Attach Bottom Panel to Back Panel
Step 6: Add Side Panels to Previously Constructed Panels
Step 7: Attach Power Leads to Momentary Buttons
Step 8: Install Optical Drives
Step 9: Install Power Supply Unit and Hard Drives
Just a quick note here; the hard drives mount from the underside of the bottom panel with two screws. There is no other retention of these drives. The pressure from the bottom two screws is all you have. I will admit they are somewhat sturdy, but I would not suggest making this a frequent flyer if you know what I mean!
