HELP! Pc case door hinge bent and case won't open

[Lumberjack_64]

When I was putting in the new powersupply for my pc I accidentally bent some of the aluminum hinge things that lock the side panel in place and ever since I closed the case it won't open! I checked for missing screws and there aren't any and I also tried forcing it with a screw driver and pulling harder it won't budge! It's and old hp case and I am reusing an hp mobo so I can't get a new case until I change cpu and mobo, this case has horrible airflow (there is only 1extake and a couple holes supply the air for a loud powersupply a gtx 970 and an a10-6700 on stock heatsink)
so I neeeeed to keep the case door open when gaming cuz after my cpu gets over 100 C it crashes btw 100c is the water boiling temp for all u Americans. So I would like someone to give me advice on what to do with the case and recoomend a cheap motherboard for the i5 4590k that CAN overclock but it's an overclocking motherboard, it also must be mid atx. Thx in advance

Actually I made a mistake I need a cheap motherboard for the i5 4690k and the mono must be CHEAP, like sub 100$
