The Optiplex sell with six different chassis types. Knowing which one you have and posting it in your Forum thread title can assist our users in troubleshooting. I will list them below =
MT (Mini Tower)DT (Desktop)MFF (Micro Form Factor)SFF (Small Form Factor)USFF (Ultra Small Form Factor)AIO (All-in-One)
As an example, a user asked what SATA port speed were on the 9010 SFF.
Forum title = 9010 SFF, SATA II or SATA III?
By the way, the answer for the 9010 SFF is =Blue SATA 0 port (SATA III)Black SATA 1 port (SATA III)White SATA 2 port (SATA II)
