I'm assuming one like this wouldn't come with mounting brackets so I need to buy them. Do you know if all mounting brackets are the same? Will they all be able to fit the same HDD as long as they're the same size? I also want to know the same with SATA cables. Are they compatible with every mobo and HDD? Basically, are those things universally compatible?
All 3.5" drives are standardized mounting points.
Anything specific will come with your case.
Either just standard holes for the screws, or some tool-less mount brackets..
Cables? Universal. 1 from the PSU for power, 1 to the motherboard for data.
