No, the reason I put it on the top is because there are 3 connections required to the MFR Grinder - power, items out, and fluids out. I have to use the block atop the Grinder for one of these 3 connections. If I connect the Itemduct, there is open space I cannot fill in (Forge Microblocks don't seem to work with Thermal Itemducts or Fluiducts, and they're transparent to light anyway). Same with the Fluiduct, there will be open space letting light in. So that leaves power, and by using a Leadstone Energy Cell which is a full block, I won't have the problem of light getting in. However, I have the unexpected problem of the Energy Cell emitting light, which I cannot prevent from hitting most of my Cursed Earth, shutting it off, effectively.
