Finally getting a new PC (Well, I hope so)

[Ruskin]

Hmm. It's a risk, I guess.

And sorry if I'm a bit dumb right now but... Wouldn't I just be able to buy an eksternal hard drive later on, if I come to realize that 100GB isn't enough? Then just store the stuff on it.

yes, an external hard drive would do fine. They are usually used for backup and storage, but I suppose it could work for that too. However, the problem there is that it is plugged in with a USB. that will cause the transfer rate from the hard drive to the computer much slower, which could bottleneck your PC once again. that is why external drives are used for storage and backup usually, not as a primary or secondary storage drive. I have never tried to run games off of an external drive, so I cannot state any personal experiences however I know that lower transfer rate = lower performance.
