terabyte drives are very common, 16GB ram is for higher end computers, most have 4, but if using Windows, that will be out of date in a year.
I don't really agree with this assessment. But you could get a computer with 4 GB RAM, if you make sure it's got room for expansion. Also, if you get more than 4 GB of RAM you should make sure you get a 64bit operating system.
