Another quick project was to mount three 3.3V 55A power supplies in a project box for the HTOL testing I've been doing these days.
I bought an aluminum project box for $85 from an electronics surplus store and bought cheap digital Volt/Amp meters from Amazon.com to mount on the panel. And following is how it looks:
To measure high current the Amp meter measures the potential drop across a Shunt rated at 200 A, 0.75 mV
The current reading is fairly accurate and serves our purpose. The shunts can be seen in the following image:

And here is the link to buy them:
