I've been considering a Mac Mini or other small form-factor computer for some lightweight server/tinkering with HPC related tasks. There's some benefit to having a faster drive in the system, but most of the cases I'm looking at only accommodate 2.5 inch drives, though they've got some headroom, and most only have SATA interfaces.
I don't feel like buying an SSD, but a Velociraptor without the large black mounting bracket, which apparently also serves as a heat sink seems to fit the bill.
The question is, without that attachment is the drive hideously noisy or hot to the point that it shouldn't be used? Any other clear drawbacks?
