Waiting on this here b/c it's not obvious to me how to mount an additional 3.5" drive in the mini-tower case of my new computer. :(

There's a cage that looks right for a 2.5" in the upper left here, but def not suitable for 3.5". I wonder if I removed that if there's something I could mount in its place that would hold a 3.5?

Mind you I can't open that guy back up (or--shouldn't) until my long-ass copy operation is finished.

That case design is a horror show. Standard practice for Dell, though.

I don't see any good place to mount a 3.5 in HDD.

If I were you, I would park that drive right on top of the power supply, with these under the 4 corners to reduce vibration and to keep it from scooting around.

Also, putting heavy things on top of a laptop is risking some very expensive damage.

@voltronic Ah--thanks for the advice! I suppose it may come to that. :( I wonder if I wouldn't be better off just buying a housing for this thing & running it as an external drive... Tho then I guess I have to power that separately (right?). Probably a PITA.

Amazingly, the new machine is pretty light, tho I totally take your point...

@rpardee
If there is an eSATA port on this motherboard, then maybe. I doubt it has one. USB will be much slower so I don't recommend it unless it's USB-C or if you need this to be a portable drive.

@voltronic ah, bummer. I do have one USB-C port, tho it's on the front of the machine, so less desirable.

I'll do a little more research to see if I can find something to actually screw the drive into & if not will go w/your idea of perching it on the PSU.

@rpardee
It will actually be superior to hard-mounting the drive anyway, as long as this system is staying in a fixed location.
