I prefer the rack-mount PC over laptops because you can't get good laptops with a lot of storage, and the portable HDD's are susceptible to being dropped, especially when they are moved around a lot. I may move to a smaller RU PC in the future, but they are a bit pricey.
Edit...
About Me:
I have been involved in music/dj'ing/karaoke in one form or another since the early 90's. I started out on two 1200MKII's and a Numark 1775 Mixer. In 1996 I went to work for a local business working in marketing and entertainment and have helped them amass 19 years worth of music and karaoke music.
Recently, I have teamed up with a long time friend to create BNB Productions after seeing that the market in the area for karaoke was fairly large and that the local DJ's were, basically, kids that had downloaded all their songs off the internet and were quite unprofessional (we plan on doing things very differently). With my experience and my partners connections locally with venues and bands, I think we will do very well.
