All aluminum like the side tanks and everything? I've only spotted one company that makes that description. They even have an aluminum expansion tank built-in!
Unfortunately, they are made per order and cost near $1000! The company started with a "Z" and these are for racing applications. Should others clone them, I'm sure they would be a good seller at a $300 price point.
Edit: For your system effort, look into a Stewart pump. You'll have considerable piece of mind for a few more bucks. Also, if you have an automatic, buy the lower thermostat too. When the E-tank breaks free from the coupling it often damages the stat from impact. Mine blew into pieces. A new stat is a good thing whether you shatter it or not. Don't go cheap with cooling replacement parts OEM or an OEM supplier only. Especially that E-tank!!!
Anything made can be made Better
