There is no widely-used "standard" for how RAID controllers handle the details of data storage on a pair of HDD's. This means that, as a general rule, when you try to move a pair of RAID0 HDD's from one machine to another, it is likely the new machine's controllers can NOT read or use the data on the old HDD's. You are left with only one option - wipe the HDD's clean and establish a new RAID0 array. Of course, this also means you lose everything on the drives. So, you MUST make a reliable complete backup of the original RAID0 array in the old machine BEFORE trying the move.
Now, sometimes it does work anyway. The odds of success are much better IF the RAID controller chip in the new machine is from the same chip maker as the old machine. That is because SOME RAID chip controller makers keep using exactly the same control algorithms, so their newer chips do everything the same as the older ones. HOWEVER, not all chip makers do this, so it's still a big risk. EVEN IF this is the case, there is also one thing that must be done correctly. In a RAID0 array, one disk is NOT the same as the other. So when the two are connected to the mobo ports, the "first" one (say, the one connected to SATA port #1) MUST be connected to the "first" position on the new mobo. This, too, is a bit of a shot in the dark sometimes, so it adds to the risk of failure.
Bottom line is that, although you MIGHT get it to work OK, you really should plan for it to fail. Make sure you have a good complete backup before starting. And then, also make sure you VERIFY that the backup is good and can actually restore everything to a new RAID0 array.
