They must have switched OEM's at some point then... my 420 ain't that light :/
I think I'll drop Turbolink off my list of decent PSU's now...
Edit: just did some more research, and found something interesting. Some Turbolink 420's have different specs - some are identical to my CWT, but others deviate from it; particularly on the 5vsb line. They obviously don't use CWT on a consistant basis.
I believe I'll eat my own words now and suggest that if you get this case, try and have them drop the PSU or substitute a Fortron/Sparkle for it.
