My motherboard bios on my download/storage box failed yesterday

I currently have a RAID 5 array made up of 4x 500GB Disks on a Highpoint RocketRAID 2310 Raid Card which stores all my music, videos and photos. I’m looking for some reassurance that the data on the array is hopefully safe?
If the array is safe when I re-install the os on the new hardware I’m buying (CPU/MOBO/RAM) will the array and all the data be there once the driver/software for the RAID card is installed, will it just be case of re-initialising the array under windows?
There is also a single 500GB storage dump drive in the box, which is where I put files before putting them on the RAID 5 array for redundancy – what are the chances that’s escaped in one piece?

...if that's all that wrong with the box (pretty sure it's just the board that has failed as the disks are all spining up)
