The main problem is that these enclosures have old disk controller chips that won't support the size (capacity) and bandwidth of today's large SATA drives.
The chips were designed in an era when the disk capacities were much smaller. The controller chip in an IDE enclosure from 2008 isn't going to recognize a 16TB SATA spinner even if you could find some sort of reasonably priced and electrically compatible conversion cable.
Furthermore, the physical clearances in these types of enclosures rarely allow for any sort of extension cable or extra electronics.
Lastly, SATA enclosures are cheap. Retrofitting an old enclosure with geriatric capacitors (and other components) makes zero sense.
