The worst part about any of these aftermarket gpu solutions is having to glue the ram and mosfet sinks on the chips. From what I understand, they are more or less permanent and you might break the entire thing by removing them if you ever needed to.
I don't even know what a mofset is, so I'd be relying almost exclusively on YouTube videos for the installation. Do you think it's worth the gamble? I can't seem to find the Morpheus II for sale in Canada, so the Accelero III might be the only option.
