First up on my list of things to do was a motherboard tray. Since pretty much everything goes on it and that determines the final width of everything, it's a little important.
I cut out a piece of 5052 Al, leaving some space at the top for tabs, but sticking to the mb dimensions otherwise.
To save some space I'm mounting the GPU vertically which requires a riser. This is a very nice one from Li-Heat.
Lining up the Lightning and figuring out my measurements.
I made three aluminum brackets that will use the motherboard mounts to hold the GPU. Seemed like the simplest plan.
With that headed in generally the right direction, I decided to work on the flip side and get the PSU mounted up. A nice little feature on the Silverstone SFX are some extra mounting points.
So it was just a matter of figuring out the final location and drilling a few holes to get it mounted up.
