The L28674-001 message is "This part is used in more than 200 products, we can not show the details" so II don't know what specific parts to look for elsewhere. I can see that the L28674-001 is missing from a photo I have. The L33681-001 lists other products which use it , so maybe I can find. It also needs L28668-001 SPS-CABLE KIT because no 2.5 disk was ever installed.
Are these what I need to add 2.5 ssd besides the ssd?
