Discussion Custom case design opinion

[ArcanumSteamwork]

Hello, I want to upgrade my mini ITX desktop to a full ATX but I don't like the cases available on the market and I can't find cases that were sold 7-10 years ago, therefore I started thinking about making a case on my own. The images show the general idea of how it should be. I would like a second opinion about it (especially airflow concerns) but bear in mind a few things:

• I don't want a front panel with USB/power buttons, these will be added through a box mounted on the desk and all the cables will pass through the back of the case
• the GPU is inside the case and it is kept in place by a PCI extender mounted on additional aluminum profiles. The HDMI ports are connected to the rear panel through a cable and a button like HDMI port

-the cost of the case should be less than 100£ so I can't use aluminum perforated panels everywhere, the panels will be made of 6mm MDF
- whole internal structure is removable by a simple rail system that connects the mainboard to the aluminum profiles
-I wanted a case that doesn't need many fans but use the ones already available on the GPU and CPU heatsink
-Initially I wanted a double chamber cube but it was too wide, therefore I opted for a taller but thinner case.
-This is not a showcase, it is supposed to stay out of the sight.

Can you make a custom case?
Absolutely. Many people do.
The case is literally just a box to mount the components in.

Be cognizant of your airflow.
You want air moving through the case, not just blowing around inside.
In one end, out the other end.
