I've had another Sonata mod idea. For reasons explained at the very end i'll not be using this mod but it might come in handy for someone else.
It's basically a mod to supply fresh air to the PSU without ducting. Requirements are a lot of case cutting and foregoing the use of the exposed 3.5" bays and lower 5.25" bays. But then again, who uses floppy drives anymore?
As you all know making a PSU duct on a Sonata isn't trivial. There's the front door to worry about. You could use the side Antec holes but they let out way too much EMI, draw in unfiltered air and let out noise.
The basic idea is to funnel fresh air from the usual front intake. For that, one must first get rid of the extremely restrictive drive cage, make provisions to actually funnel the air into the PSU area.
Although I did the drive cage removal part, I only took an explanatory pic of the 3.5" drive bay mod.
I will be suspending my drives from a drive bay sled that'll go into the top slot. This setup will naturally block air into the 3.5" bay but someone who rests their hdds at the bottom on sorbothane or uses the lower drive bay for hardmounting could explore this possibility.

and the conduit to funnel air into the upper parts of the case
That's a 92mm Panaflo. One could drill holes into the two small raised thingies on that bay to mount the fans and cut open the area in between.
Add to this setup a ducting mod that runs along the support bar into the 5.25" drive bay, tape up the holes on both sides of the 5.25 bay and you have an L-shaped PSU duct.
As I said, I'll be using a cheap & easy suspension so I won't be able to use this mod but who knows? maybe someday I'll dream up a better suspension mod and actually go ahead with this.
