Internal DVD to External

My External LG DVD burner just kicked the bucket and I was wondering if I could buy an internal dvd-+rw and install it in the externals enclosure?
I thought it was a good idea until I though about the drive speed difference and started wondering what kind of compatability or heat issues might be present?

Thanks for any help;)

If you have a philips screwdriver and can figure out how to take the enclosure apart it shouldnt be a problem. Two of the three enclosures I own I switched the drives in, so it’s not that difficult. The only possible problem really would be an incompatibility between the enclosure and your new drive.
