I was more concerned with the question of whether or not it would accept their expansion bay units. Though the CPU power might be a factor if I decide to ever use any of its server features, such as web server or VPN host. Also, you're right, maybe I'll use it to transcode stuff if I can figure out how to set it up to do that.

Which ones in their inventory have both of those features (compatible with the expansion bay, and also, fast processor)? It's hard to tell from just browsing their web site.
