Hello, the 535 series no longer comes with 3.5" mounting kits like the older versions.
Does Intel sell the mounting kits separately?
The Intel® SSD 535 Series does not include the mounting bracket in the box as some previous SSD's.
Please keep in mind that this drive is mainly used with low consumption systems, like ultrabooks and some laptops; also, most of the newer desktop computer cases already have slots for 2.5 inch drives.
Intel does not sell the mounting kit individually, however, you might find some in online stores. Also, it should work well with any standard SSD Mounting bracket 2.5" to 3.5" from reputable manufacturers.
