Spacers leave very little space for the fan on each level. I use a POE hat and this didn't leave room for it and a fan. I screwed up the spacers a few levels, but the extra work took away from the overall value. For 4 blocks I could leave them in their own suitcases. I was able to place one on the top level by putting the fan on top of the stack.
