The BLMS 1590A Powder coated enclosure is here. It comes with screws. It's diecast aluminum. It's shrinkwrapped.
The finish on these are not perfect 10s. They're a solid 7. They are good enough for 99% of most applications. The finish is tough, not as tough as the best powder coat you've ever seen but way better than what you can achieve with a spray can. Speaking of spray cans, these things take paint like a champ. You can easily apply one decent coat of a cool color and decorate to your hearts delight. You'll have a great looking design that is going to save you time and money on doing the whole sand, acetone bath, prime, sand prime process.
There are LOTS of different enclosures called the 1590A on the internet. Please check my measurements to make sure this is the size you want.
