Windows NT sp4

Hello all,
I would like to buy Windows NT, for my PC, and I found one for sale with sp4, included.
Will this support USB connections, so I can use my scanner, printer, tablet etc. ?

I know that NT a while back did not, but I cannot seem to find a stright answer, for the version with service pack 4.

Can I go ahead and purchase it ?
Does it require a particular processor, or is it as simple as install and go ?
Regards, Roby
