I've had my p180 for months now, and ever since I completed building my hardware in it the lower drivebay has been stuck

Now the badpart is that I only have one hardrive (Seagate 250GB) And it's in this drivebay..
I've tried just about anything to get it out, I took out the other sideplate and pushed on it while pulling from the other side, didn't work.
Took out all the hardware and it's still stuck!
And yes I didn't forget to take the thumbscrew out

Some help would be most appreciated since the little bugger gets quite hot (40-45 degrees with this weather)
T.i.a!
