Good for music apps? (Score 1)

I'm looking for a small PC just like the Shuttle, but one that can hold it's own when it comes to using it as an 'instrument' in live shows, with up to two or three external midi controllers. I have all the necessary software to do what i want and it works great on my home pc which is a freakin mammoth tower, something I don't want to lug around to clubs. I've also heard from various sources that most of the apps I use aren't friendly with VIA architecture. Any suggestions? Has anybody done this?
