Not easily; the metadata format stored in last sector on each HDD is incompatible between brands. You should get the data off first and backup it somewhere safe, then create a new array and copy it back.
If you made a RAID1 you can simply break the array and connect one of the disks to a non-raid controller.
If your motherboard broke or you don't want to connect to your old motherboard, then you can access/read/recover the RAID using Ubuntu Linux livecd. If you want to try that, simply download Ubuntu and boot it up, having your disks connected to a non-RAID controller (i.e. set controller type to AHCI or IDE not RAID in the system BIOS). Let me know if you require more help on this.
