Connecting 5 Laptops into One PC

My laptops getting old and so are my kid's computers (Most of them are out of the house)

I’ve decided to build this pc that sits in the basement and I don't have to tend to it very often.
I want to set this pc up so that my kids or myself can log into at any time. “I'll just call it an External computer”

The way I would like it to operate is:

We are still able to login to our old laptops but instead of using our old laptops memory, processes and hard drives we're about to use the newer higher powered external computer.

Log in to it somehow like VPN, Remote Desktop, Create a website for log in virtual pc. I'm never really had much luck with using a virtual pc or desktop, but that was a number of years back.

I've decided to build a pc with the parts below. I started out just looking to add an external hard drive but ended up trying some and I really need some input and guidance.

Base OS and Applications
  1. Microsoft Office 356 Pro
  2. Microsoft Windows 10 Pro
Can this be down?

  • Will each user has their own profile?
  • Will I need to buy additional operating systems?
  • Sharing software?
  • Should I partition the drive into 4 sections? At times, I like to remain anonymous

forgot the Thermal Paste. but I'll pick some up

What am I missing or need to add
 
Just use the new computer for the home base for you cable/dsl and router.
What do you mean by the kids being out, are they in college do they still live with you ?
You might want to look into setting up a static ip address for each computer.
Just beware those ip addresses can be used inside of your home not outside or long distance.

Hardware wise I don't recommend toshiba to be the main drive for any os.
They are prone to fail alot more faster than seagate does within a year.
