Search for countertop Brutus 20 for ideas. I did that for a year. Having the cfc inline was nice. By recircing at the end, sanitation was a breeze.
Next, I turned the same system into a herms, because I get bored unless I'm tinkering mostly. I have an ekettle and a cooler, and the kettle has an ic built in. I use the ic as a herms coil during mashing, and I circulate ice water from the mash tun to cool after boil. Works really well. For sparging I originally did the recirc of the Brutus style, but got frustrated at the efficiency... I like BIG beers. Now, I batch sparge, using buckets to hold the wort while the brew kettle heats the sparge water. I like this a lot. Great, repeatable efficiency, closed system that is sanitized by recircing after the boil, and only 2 vessels. I don't count buckets as vessels. 2 pumps are loud though... I also brew in the kitchen.
