Mine is shown below and is a Work in Progress (same goes for just about everything in my home brewery).
If you're looking for inspiration, mine could use the following improvements:
*A GRANT at the MLT outlet would make life much easier
*Raising the mash cooler off the ground (I use cinder blocks now, but they aren't pictured)
*Pump housing and sample draw (like the BYO pump tool box project)
*Sparge water manifold on the cooler lid - this model of cooler does not hold temps well, and cracking the lid to sparge doesn't help!
*Plate chiller
*More tubing and valves to switch from vorlauf to kettle
*More permanent sparge manifold - the current design likes to detach mid-mash (pictured)
