The 1590XX White Powder Coat enclosure is here. It comes with 4 screws. It's diecast aluminum. It's shrinkwrapped. It's AWESOME.
The finish on these is solid, not a perfect 10. 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, etc. process.
The internet isn't in complete agreement on what the 1790NS/1590XX official size is so you should check my measurements just to make sure we're talkin' 'bout the same thing.
It measures 145 x 121 x 40mm or 5.7" x 4.7" x 1.5"
