9. HP Pro 3400 MicroTower PC
It's amazing to think that HP was considering pulling out of the PC market but then the crazed CEO left and life went back to normal. If you need a solid PC system that's going to work day-in day-out then the HP Pro range should get a good chunk of your attention.
The 3400 range is based on a no-nonsense microtower system, which comes with Windows 7 Pro 64-bit a basic 2GB of memory and a low-cost but capable AMD Dual Core E2 3200 processor. With an optical drive and a roomy 500GB of drive space this system has everything you need to get your business up and running, while remaining expandable as you go.
Support costs are kept to a minimum by the basic 1-year collect and return warranty. There's nothing here that's going to change the world but with HP's reliability it's a system that you can be sure will keep on running.
