BPI-R1 remixed cooling case

Modified the design:
- added holes ( done in tinkercad.com):
* cooling on the side
* SD card for easy swap
* custom DC connector (goes to bat power)
* moved WiFi holes down a bit
cannot use WiFi antenna and HDMI cable at the same time
* covered HDD screw hole as I saw no real usage (need to take mobo out of the case to change HDD anyway)
- redesigned top cover in 123D Design to fit a fan
- made a cap for SD card (did not used it yet)

Fan used: [aliexpress link] (https://www.aliexpress.com/item/USB-2-0-Connector-60x60x10mm-6010S-60mm-5V-Computer-CPU-Case-DC-Cooling-Fan/32598696220.html?spm=a2g0s.9042311.0.0.KXeAqL)
* hooked up to 3.8 volts instead of 5. Makes same noise as a laptop fan at medium.
Connector: ? (refurbished from an old car vacum cleaner)

P.S: cpu temp stays at 37 degrees on idle using lamobo-r1 linux distr (with HDMI connected)
