This might be a long shot, but can any one point me toward a detailed diagram, or no, what the exact mounting hole sizes are are. I have got the Enthoo Primo case but need to try to mod it to fit an XL - ATX board. I already have the board the MSI Xpower, and I could easily make a template, but when it is picked up it makes a lot of creaking sounds, from the weight of the heatsink I guess. So I don't want to handle it too much. Cheers guys.
