Greetings. Two years ago i purchased a $300 hp prebuilt. Late 2016, I added a EVGA GTX 1050 ti and a 500w EVGA PSU. The gpu didn't fit through my side panel and i could no longer keep my computer in a traditional tower position, but instead had to lay it down and remove the side panel. I currently have my setup on a small shelf, and there are an immense amount of cables. Most people nowadays are much cleaner, with just a tower and a monitor on the top of my table. How would i start to make everything easier again, where i can finally put my tower on the ground with a closed side panel and have managed cables, etc. I am thinking of getting a new case, but i don't know how to keep the gpu from taking off the mother board when it is in a position where it is against gravity.. i don't know how system builders do that. i also use two power supplies, and my new power supply has many cables I don't use and are all just packed together right outside the case. Any help will be greatly appreciated.
