You can browse the forums and see what PCs I made in the last few years ... and most of them were limited by my budget. If I had money, I wouldn't even touch the "case" mentioned in this thread, as many other cases give much better options. If I had the time, money, and proper tools, then I would cut and paint every case I would have in my hands, as I haven't seen even one perfect case that I wish to keep in the form as it was designed.
I don't get all the excitement about the functionality of the motherboard box ... those who were benching on boxes know what I mean
Try to install regular components on this open-frame thingy, and you will have a lot of cables everywhere. To have a very simple build in open space "case," you need all custom cables and a lot of playing with cable management as the manufacturer doesn't give you anything besides a simple frame for mobo ... but hey, it's 45°, so pay us ~$170. The same is about the mentioned in my last post Streacom, but they at least add some more parts and options sold separately to expand the functionality. Still, their quite simple bench tables or open-space ITX cases cost $120-200.
Here is BC1 Mini - if you want, the stand can be ~30° or something -
https://streacom.com/products/bc1-mini-v2-open-benchtable/ It costs ~$100 in some stores. It's nothing really new as similar products were around for 4+ years.
Here is something a bit weirder -
https://streacom.com/products/da6-mini-itx-case/ I won't hide I wasn't really happy about it, but it's a longer topic. Here are some photos of the build I made for the review -
