It is. I ordered the tool kit and keyboard, watched the video. Looks easy enough. If I get stuck I'll bring the part to apple. Thinking of upgrading to a 7200RPM drive also, hard to tell which are compatible on amazon, anyone know for sure?
Apple won't repair your machine using a part other than one they pull off of their shelf, completely against their policy. On top of that they are forced to send it to the repair depot for a tier 4 repair due to the accidental (liquid) damage, costing upwards of $1000.
With that said, and only mentioned to help you avoid wasting your time, it's a pretty straight forward repair. The top case is a little strange to pop off once all the screws are removed but from there it's just removing several (10'ish?) small screws and bending a few tabs to separate the keyboard from the top case. If you take your time you shouldn't have any issues assuming the liquid damage didn't affect the logic board or top case. Just remember to stay grounded to avoid ESD damage to the internal components and follow the iFixit walk throughs step by step.
As far as hard drives go, really just about any 2.5" wide, 9.5mm tall or thinner, SATA hard drive will work with your MacBook Pro. You'll want to make sure to transfer the carrier/mounting pieces from the original hard drive to the new one but aside from that it's about as difficult as replacing your keyboard.
Best of luck!
