Answer to: Replace hdd with ssd and move hdd to optical bayThat's a slightly convoluted upgrade, so Heads up: the stock internal 3.5" HDD's have a new type specialty in-line thermal temperature sensor cable, and improper reconnection or removing that is what causes the HDD's fans to go crazy or fail the Apple Hardware Test. But most importantly, I believe the optical drive bay can only handle a 2.5" HD (or smaller) SSD: I think the 3.5" HD form factor is too fat for that optical bay space. You have probably already found/googled "27-inch iMac (2011) Hard Drive Installation Video" to see the skill level and tools needed for proper and correct surgery for opening up the 2011 iMac 27". Also, when you install an aftermarket SSD drive into a Mac, TRIM is not enabled, and you can research what software tools/commands you can use to enable that if you wish. And if after all your upgrades still cause your fans to go crazy, you can stabilize that thru the usage of a 'Fan Control' software for Mac OS X as a last resort.
Answer to: Groupdhead, where my portafilter fits leaks badly when brewing.Might that 'partial piece of black plastic' have been a piece of hard rubber? If so: Google: Starbucks Barista Group Head Gasket (Don't worry if the name "Saeco" shows up when you search parts and repair guides: The Starbucks Barista is made by Saeco and relabeled with the Starbucks name...) The Group head gasket is a fat custom o-ring that your portafilter rim contacts when you insert and twist your portafilter properly around the group head. This is a common area of leakage/spurts when that o-ring inevitably wears down, and an old one may have become brittle and a piece of it may have fallen out. ALSO, double-check >>: The Starbucks Barista uses a pressurized portafilter, with plastic pieces and springs, etc. So take a look at ifixit's guide to Repairing the Starbucks Barista Portafilter, in case that broken/partial piece of black plastic came from your portafilter assembly... Sometimes these parts have to be ordered from 3rd party vendors, not usually carried by local vendors, but inevitably you can find a...
