The first thing you notice about the HP ProLiant ML370 G5 is its size. It’s massive, with room for not just the latest dual-core Xeon processors but enough memory, storage and other options to suit a wide range of applications. Because it’s very solidly built, the huge desk-side tower housing the ML370 is extremely heavy, requiring two people to lift it. It can also be rack mounted if required, although it ends up 5U high and the rack would need to be well anchored to prevent it tipping — especially if you choose any of the optional extras. Our review model, for example, came with a redundant second power supply and an additional bank of hot-swap fans. You can also add a lot of storage, making for a very heavy and, at times, quite noisy system.
