Conclusion: The GS1000 Plus finds itself in a bit of a bind. At £140, it's not a cheap case. It's out done in several areas - particularly cooling, but also adaptability - by other cases which are often much cheaper.
Summary: The Zalman GS1000 Case is available in two color options and is made from aluminum, steel and plastic. The side panels are aluminum, inside is steel, but the remaining outside is plastic. At the front there are four 5.25" drive bays but two have a 5.25" to 3.5" drive bay adapters.
Conclusion: Despite it's admittedly excellent cooling ability, we still have a lot of reservations about the GS1000. It's significantly noisy with the included fans which is a major let down, especially as in the past Zalman is a company you'd associate with quiet, well-built and innovative products.
