The problem with this one is still what we covered before. It's a little light and no OS so you are unlikely to get a good price above the part costs.
The OS alone is worth a bit as a great install with recovery media is worth hundreds on its own. But I have encountered those that build PCs that can't wrap their head around this area. That is, they think nothing of installing Windows but we are solidly into the consumer age. If they machine is not ready to use and can not be recovered without a guru or hundreds at a service counter it's just another clone.
Clones are plentiful and cheap. How will you make this unit stand out and not be yet another Ebay clone?
