PowerSpec USB 2.0 External 3.5″ Hard drive enclosure. $19 I needed a case for travel so I wanted something cheap… I had an older EIDE 300 gig drive laying around so I got this case. It’s fanless and fairly cheap at $19. It has a simple and effective design. It’s basically 2 metal plates that sandwich the drive with steel mesh all around the edges. Since there is no fan, operation is quiet. The drive can stand vertically or flat on your desk.
