Rekordbox DJ with desktop PC?

I'm thinking of a buying a DDJ 1000 so need a computer running Rekordbox DJ - which would usually be a laptop.

I don't have a laptop but have 2 high spec PCs (hence me not wanting to buy a laptop) so I can use one of these to run Rekordbox DJ with the DDJ 1000?

I assume yes but there a coupe of issues which I'm not sure about though?

1. Where the DDJ1000 will be, I won't be able to see the PC screen or use the keyboard/mouse.
So, If i plug an external small monitor and sit it by the DDJ 1000, will this work ok or do i need to use the keyboard and mouse with Rekordbox DJ?
Ideally If i can select/load the tracks from the DDJ 1000, just having the external monitor would be all I need right?
