As prices of SSD's fall I would say its better to actually have it inside your imac than outside it![]()
I was more concerned with someone less likely to buy it since its been altered.
Not accounting for your time or the risk of breaking something while you are changing the hard drive, an OEM machine at a lower price probably attracts more buyers.
That said, you don't have a lot to lose by trying to sell it the way it is now. If that doesn't work out, you can always change it back to stock and try again.
Good luck!
Should I spend $20 to upgrade to ML before selling?
If I had to send in my iMac for AppleCare, does having the SSD that I installed void any warrranty?
That would be a nice gesture. However, when you purchase the ML upgrade through the App Store, your account/credit card will be forever linked to the purchase. When a update is released, the buyer may be unable to apply the update without your account password.
You can still update mountain lion if you don't have the password for the appstore.
I was thinking the App Store always asked for my Apple password whenever it downloaded any updates unless I had previously selected "remember my password" on that particular computer.
I know the last IOS update seems to have eliminated the need for a password on updates (used to require it even on FREE apps). Perhaps they are starting to apply the same rules to App Store downloads?
