I know Josh is probably busy and overwhelmed with emails so I'll ask here:
-How likely is it for the September preorders to actually ship in early September?
-The preorder is limited to 127 units, has that limit been reached yet? Not sure if the website will reflect the limit actually being hit.
-So HDPlex replaced their 300w DC-ATX psu with a 400w version. Will the Dell 330 watt AC-DC adapter be enough to actually provide 400 watts? Interestingly enough the 400w HDPlex psu has an option to bundle a 300w AC-DC adapter with it, I wonder if that will be enough to actually push 400 watts/
-How likely is it for the September preorders to actually ship in early September?
From my knowledge historically he is usually on time unless some part of the manufacturing process delays which he will announce it to everyone why. It's not his first run so I am pretty sure that won't be a issue to much.
-The preorder is limited to 127 units, has that limit been reached yet? Not sure if the website will reflect the limit actually being hit.
Correct he may not have hit it or he could be planning to produce more just in case. As long as your pruchased one I wouldn't worry. Most likely he will full fill it.

The Dell brick only provides 330w. If a brick is rated for that wattage like 309w or 330w you should assume that is the limit either due to component or thermals. They are not rated for higher wattage.
