Hope everyone is doing great. I currently have a XFX 6900XT Merc Black and I know that you have the 11956 that fits my particular card but while continuing on my hunt, I saw the 11945 that is for reference models. My question is was the acetal option offered on any other cards? As one who doesn't like RGB and avoiding acrylic (for theming purposes), was looking for an alternative in black, as it is looking like I may t need to sell my card and "downgrade" to get the waterblock wanted. Thanks in advance for any info.
