DenisThe custom made metal enclosure is arrived two days ago from Varisom in Portugal. It looks nice (color is RAL5022) and it's well manufactured, robust and should survive real mechanical stress. It was my first try to order a custom made mechanical part and there was few issues but nothing that cannot be fixed and easily hided :). It's total weight is 4.9 kg.
Please take a look and let me know what you think:

I just made some quick measurement of internal temperature when 300 W load is connected (2 x 150 W). It's 35 oC or 7 degrees over ambient temperature that is currently 28 oC.
Are you sure? yes | no
looks absolutely beautiful! I have some questions/comments.
There seems to be no space to use some crimp terminals for the the Meanwell module cables
What temperature are you expecting to get inside the enclosure?
Does the power module needs to be de-rated as it is designed to be cooled by natural convection?
What do you think of using the power supply vertically to save space on a desk? A command could be sent to rotate the LCD content thus allowing for easier reading in that mode

That's right, there is no lot of space on the left side of AC/DC modules but that is enough to use wiring with ferrules at the end to make good connection.
Internal temperature should be no more then 30 oC over ambient temperature. I didn't measure it yet.
Chosen AC/DC modules (Mean Well LRS-150-48) offer full power with natural
convection from -30 to +70 oC. Situation here is better because fan regardless of it's position still affect area where AC/DC modules are mounted.
Yeah, it's possible to rotate a complete design from "landscape" to "portrait" when e.g. AC/DC modules or mains transformer is on the bottom and power modules on the top. I started a complete thing presuming that everything will go into some of available enclosure (they are in general in "landscape" form) not the custom one. What to do know, it's too late at least for this revision :(
