HP Vectra VL420 PA5765A

Once you've put the lid back on you'll notice something else - it's incredibly quiet for a Pentium 4 machine. Sacrifices have been made with a fan-free graphics card and a minimal 185W power supply, but HP has also introduced its UltraFlow cooling mechanism. This initially involves plenty of ventilation holes at the front of the case, which don't interfere with the Vectra's serious styling, but also reduces the need for intrusive active cooling inside. Then there's the cooling system itself, with a CPU fan that adjusts its speed according to the heat generated.

This design, along with the superb DVI flat-panel option, warranty, support, flexibility and performance, make the Vectra the perfect business machine. There's no doubt that you could get away with much less power for average office work, but you're also getting an element of future proofing for tomorrow's applications, and the Vectra will be happy for at least another two or three years. All of this makes the HP Vectra VL420 PA5765A the business PC of choice.
