I'm preparing to edit videos and images and found a reasonably priced HDD that fits my storage needs, but my older computer case has nowhere to mount a 3.5-inch drive. I already have an NVMe drive, but it isn't large enough for everything and I can't delete its current files. An SSD would be too expensive, so I'm looking for a safe, practical way to install or use the HDD without damaging it or risking my data.

The safest solution is to mount the HDD in a separate drive cage or bracket, then secure that cage inside the case with strong double-sided tape or another suitable mounting method. Avoid letting the drive move around freely, and make sure it isn’t blocking airflow or pressing against any cables. Taping the cage is preferable to taping the drive itself because it avoids residue and makes future removal easier.
If you only need the storage occasionally, a USB enclosure is another option. It’s simple and avoids modifying the case, though internal SATA will generally be more reliable and faster for large video projects. Use a good enclosure and cable, and don’t disconnect it while files are being written.
As a temporary option, you could place the drive flat on the bottom of the case, but it should still be secured so it can’t slide into fans or pull on the cables. Remove it before moving the computer, since a loose mechanical drive can be damaged by impacts.
A custom bracket, including one made with a 3D printer, could work if there’s no suitable commercial drive cage. Whatever method you use, keep the HDD away from fans, leave some airflow around it, and make sure it cannot short against exposed metal.
You can position the cage horizontally or vertically, as long as the drive is firmly supported and the power and data cables aren’t being bent or stressed.
