Is my graphics card adequate for gaming, and is my DVD reader and hard drive ok?

I'm going to be using this system for gaming, mainly less demanding games like Minecraft, so is this graphics card good enough?

Also is this DVD reader adequate for just installing an operating system and maybe Microsoft Office?

Lastly, I want a 1 TB hard drive but they all look the same with different prices. I don't know which hard drive is best for me to get, because I want a good quality hard drive which will last a few years. Is this OK?

Thanks to any answerers!

Added (1). I don't mean ultimate quality hard drives for £150, but just one which won't break down straight away.

That graphics card is fine for games like Minecraft but I would still go for a better one for future games. Hope this helps!

Yes it is.

Okay firstly the GPU is fine (graphics card) that is one of the best cards for the money right now so good purchase!

The DVD reader isn't important at all any old drive will do.

The HDD is different the drive you are buying is very over priced and is for RAID configs. If I was you I'd get the Western Digital 1TB Black drive!

This is really fast and reliable one of the best HDD right now!

Both are ok its not the Best card but it will be fine for gaming
