Which mini PC?

I bought a smartboard from SMART Technologies for my lesson preparation and now I want to know what you can recommend for a Mini PC that is connected to the SMART board. It should run smoothly and the SMART Notebook should be able to play freely.

Thanks in advance!

PS: Not much more expensive than 100 euro

So you will hardly find anything that is not more expensive than 100 euro! With 500 Euro Pcs that you buy ready, the assembly costs around 100 Euro… So spend at least 200 Euro if it shouldn't lie
