Are there any case on the market which can hold a UDOO X86 and also one of those thicker 2,5" HDDs with a z-height of 15mm?
The acrylic case can be extended in height by adding extra spacers. The bottomplate is predrilled holes for mounting an 2,5" HDD https://www.udoo.org/docs-x86/Hardware_&_Accessories/Official_Accessories.html
