Don't know if you'll think this is relevant in this thread backslang but I've just dealt with the Cust Service dept of Coolergiant here in the uk, and they were excellent, I'd ordered a Coolergiant 485w from one of OcUK's competitor's and an ATX Ver 1.3 arrived instead of the ver 2.0 I'd ordered.
Firstly Coolergiant sent me the necessary cables to convert to 24 pin and extra sata power connectors.
Then I found out to my horror that the coolergiant range are a good bit longer than a std PSU (26mm), 166mm compared to 140mm.
This resulted in me not being able to refit the top of my case without removing a cooling fan which was now fouling the new psu.
I emailed Coolergiant and they're gonna swap my Coolergiant for a Noisetaker which is only 140mm long.
I think that's excellent customer service, I don't know what the other PSU manufacturer's are like to deal with or even how many are contactable here in the uk, but Coolergiant get top marks in my book.
Cheers
