Use two desktops?

[Chezzo44]

I have two Small Form Factor Optiplex 760. Is there any way to either use parts from one to improve another or to upgrade them with new CPUs, GPUs, etc.? Any help would be greatly appreciated.

Well, you could get a new case and take the optical drive and HDD and have a nice custom computer with alot of storage and optical drives. That's about it though. You could upgrade the graphics card.
