I'm keeping my Case+fans, fan controller, Optical Drive, GPUs SLI [unless I decide to sell them] and HDDs.
I might get rid of my current SSD and get another one. I don't know right since I'm still using it with no issues. Other than that I'm getting a newer PSU and pretty much everything else not listing above.

Generally speaking I tend to upgrade my PCs to keep them limping along so long that when I do build a new PC about the only things I can salvage are the drives. Even the case is usually in less than ideal condition after 5-7 years of usage.
Stop complaining. I could have done this more painfully. - Dryad from Sacred 2.
