My inital intention of this build I did about 5 years ago was to fit as many hard drives as possible into one cheap case.
Most regular cases had space for 6-8 3,5" HDDs max, I had around 10 at the time and was going to upgrade to 12.
I wanted them to power down individually, so a server case would not help. Also this was my gaming machine, so it should hold a graphics card and everything else too.
I decided to buy an old glass table to do a cheap and quick DIY table case.
"quick" took several months and hours of work in the end. Wood work, metal work, wiring and issues on almost every step of the way.
I learned a lot and it was so much fun but it did not come out perfect at all.
Sorry for my messy desk and the poor picture quality, as I mentioned this was a long time ago.
Please be nice.
