Supermicro SC505-203B 9x 2.5" SSD Mounts

These brackets allow for: 

• 9x 2.5" SATA/SAS SSDs to be installed in a Supermicro short-depth SC series chassis.  Built on a SC505-203B, probably works with others.
• 40mm Fan at the rear
• Alt model to allow for easier PCIe card installation/removal.  Does cost half a bay, fine if you're using a slim SSD etc. 

Understandably it's a tight fight, so installation order is key.  I found the easiest way to be: 

1. Mount pins to all middle rack drives, and the sides on the drives facing the middle bracket. 
2. Screw drives in to front and rear brackets. 
3. Align all the drives in the brackets, ensuring all the mounting pins fit in the holes. 
4. Transfer the racks into the chassis. 
5. Swear, because one of the drives probably fell out of a mount.  Fix. 
6. Screw down in to chassis. 
7. Cable management, connect all cables. 
8. If using the alt bracket for front, install PCIe card and riser.
