Barrow block arrived. Looks decent. Interestingly the internal flow direction is guided by plastic separate to the Acrylic cover, in places. Can't remember who else does that.
Came well packed with a good retail box and all the trimmings, including English instructions.
Problem is, I'm slightly tempted to just sell it with the RVII and get a 5700XT 50th instead.
If RAL is exclusive to Navi and not being brought to Vega, then to me the lower lag and greater 'connectedness' is more than worth the lower FPS.
