Here’s an update from the Dell site to include everything you need. MS Office and an extra hard drive.
Here’s some AIO (All-in-ones) from PC world.
I like the price and specs on the Lenovo but don’t like the look of it.
After that I’d go for the Dell again.

You’ll need to buy MS office separately.
So what has the first Dell got that makes it so expensive?
Well, it’s basically top of the range, modern and it has a touch screen.
