Does such a HTPC case exist?

if you want speed then get 4 x wd velociraptors 600gb for $180 each and u get near-ssd, or if you want more storage then get any 7200rpm 1tb drive from a quality vendor

I think I definitely want something that doesn't need airflow.
I figured out how I would mount the hard drives, and that involves literally stacking them, with a thin peace of foam or felt in between the drives. Is this doable? or will I run into overheating issues?

instead of felt maybe 2sheets of alluminium or steel. If for some odd reason a drive does overheat the felt might melt and ruin your drives/light on fire.

the velociraptor only has the cooling fins because they need something to fill the space. It is just a tad warmer than the normal drives, just heapes faster.

avoid having flammable/burnable things near warm appliances (cpu is right next door)

you can even remove the fins alltogether, they are just there to ramp the sizen upto 3.5"

I don't have to use felt, i just want something soft like rubber to reduce vibrations and prevent the drives from rattling.

And I need 2.5" laptop drives.

In your case it would be better to make a something like

Racktop
Rubberpad
Hdd
Rubberpad
Racktop

Repeat this will insure that all the vibrations are absorbed.by rack top i mean where the hdd screws into

what rack top? The way I'm thinking of, the hard drives will be literally STACKED. there will be NO screws or mounting points.

I've actually found a few, all with shitty power.

here's one: Silverstone Slim HTPC/Desktop Case - SST-PT12B (Intel DH61AG chassis) | eBay
requires a motherboard with built in power, and has a lot of wasted space below it.

So what you are saying is that thr hard drives will just hang loose

pretty much. they'll be boxed in so they don't move around, but all that's holding them apart is a little bit of rubber or something.

The bit of rubber would work but you have to fix them down
