According to some specs that I've seen, some fans are only rated to run continuously for about 18 months. That may be fine for many home PCs which spend more time off than on, but no good for servers. Even more so if they're fans that can't be easily replaced (e.g. ones that are bonded in as part of a CPU block or the graphics cards, or deeply embedded in the PSU brick). I think server fans ought to be standard models, though long-life, easily replaced, and using ducts to the parts that need directly cooling. > Seriously ..

I can do that here, but only from quite limited choices. If I wanted specific parts that they didn't have, I'd have to buy them directly from some supplier, if I could find one, not from a shop. They won't deal with anything else, and will give you all sorts of excuses about why. I really don't beleive that they couldn't buy anything that I could, nor that they can only buy parts in quantity. And that's if I just want parts to build a box. On the other hand, if I was to get them to build me a box, it's quite common for you to choose a 128 meg video card, a 140 meg hard drive, but they'll pick the particular parts, and they may well be different from what they told you while you were negotiating the package. Sometimes that's because they found what you wanted to use didn't work with each other, sometimes it's because they'll just do whatever they want to. -- Don't send private replies to my address, the mailbox is ignored.
