Certainly the empeg meets your requirements as to display. The hard drives are fairly easily upgradable, but they're laptop hard drives, so they cost a little more than regular desktop hard drives (and don't have as much capacity), but you could still get, currently, 200GB worth of storage in the empeg for a little less than $400 or, more reasonably, 160GB for less than $275.
