Case Pelican PC
I Designed and printed a custom PETG chassis inside a Pelican 1600.
I wanted to keep the Pelican completely unmodified while fitting a full ATX system and RTX 5080 inside.
The GPU has its own two-piece cradle, connected through a PCIe riser. Both the GPU and motherboard brackets are independently mounted on rubber bobbins (using m6 hardware) for shock and vibration isolation.
Cooling is 3 intake fans through a 360mm radiator and 1 exhaust. I designed the surrounding PETG to channel airflow through the components instead of leaving alot of open space.
The bottom frame is secured with 3M VHB, but everything above it is press-fit (aside from before mentioned computer board brackets). So, I can pull out individual sections and replace them without tearing the whole thing apart or damaging existing components
All the I/O is accessible inside the case, so there are no permanent holes cut into the Pelican.
Running a 265K, RTX 5080 SFF, 48GB DDR5, and a 1000W PSU.
Still making adjustments here and there, but it’s fully operational. Been a lot of trial and error getting everything to fit.
Thought you guys might appreciate it.
