I don't think you need to take it apart again by the look of that lot. Marvellous

I reckon your MBP is going to be fine for a while yet.
Punishing tasks are not for a mini, they get just as hot, my video customers have to sit them on cooling pads like the MBP. If you have room for one and you have a lot of hard transcoding work to do I would seriously consider getting a used 4/5,1 Mac Pro. There will be a lot of them on the market once the new black can is available and the prices will drop. My old 2008 3,1 is pretty outdated by Mac Pro standards and much slower than the newer models but the twin 3.2 quad core Xeons and 32gb ram takes more punishment than I can throw at it with aplomb. I should have bought one years ago and will be upgrading it to probably a 5,1 with twin hex core chips when I get one cheap enough transferring all the upgrades and drives into the newer model. It's already fast enough for me as it is!
I paid $640 USD equivalent for my tower, $540 in reality cos I sold the raid card on eBay!
I could always abuse my work laptop! LOL, I dont really care what happens as my company gave it to me (but not to own).
