But not really worth it, right? It's a $200 upgrade from the i5 to the i7 from Apple, so.... I guess if you sold the old CPU? But then you'd have to hope if you had a warranty claim that Apple didn't notice the upgraded CPU. RAM and hard drives are one thing, but.. CPUs? Hmm... Reading back it looks like he had one lying around, so why not, eh?Still, very awesome to be able to do this down the line if needed.Waiting to hear on the definitive type of tape used to close this up so I can replace the internal disk at some point.Was this a Samsung 830 128GB SSD in there? I'm very intrigued by your benchmark results. Your speeds look great. For reference, I tested several Thunderbolt enclosures and got 360/320 read/write using a 256GB Samsung 830. So it looks like you do get better speed using the internal connection, not that the average Joe (me included, I'd wager) could tell the difference between 430/310 and 360/320 on a day-to-day basis.Great work, by the way, R.OG!
