Like I said ... and humbly ... Relegate those older drives (even the opticals) to cheap, external, USB2.0 enclosures. They will be portable and more flexible and, most of the time, they will not be powered-on ... and, so, will last a long time ... If you ever need an extra burner, for batch-burns, you can hook one up ... same w/the HDDs ... USB ... in a drawer ... OR ...load all your family media onto the old HDD, and send it to a family member for "off-site archives".
... There are even ULTRA-CHEAP EIDE>USB adapter cables, so you won't have to pay for the actual enclosure and can swap devices quickly ... (that make sense?).
... Leave the older parts out of your build ... you got your money's-worth already.
