Digging around little more and guess this might be the best option to externally power a 3.5" hdd with an LPS?

Unless there's other option that can provide better SQ/cleaner power for the 3.5" hdd...

 

Given it's small form factor, it almost certainly uses switching regulators, which is not a good idea for the best SQ.

True, and I think you are correct that these use switching regulators. However, I don't see any other way to power a 3.5" HDD without using an hdd enclosure which always convert into USB out.

Or is there an alternate option out there?

 I don't know about presently available enclosures, but some had an eSata input option as well.

It was even possible to extend a short SATA cable from the PC through an opening in the PC's case through an opening in the enclosure.

 There are 12V 1.5A SMPS adaptors available on ebay but you would need to check the output plug's compatibility.

 Sometimes , despite being SMPS, you can obtain an audible improvement by earthing the -VE side of it's output.
