Just like buying a car, you need to know what your home-office PC is for. It is very common that people bought a powerful and expensive desktop more than what they need it for. Sometimes it is better for you to buy a new PC rather than upgrading because of change of technology. Some people would like to build their own and others would like to settle with reputable brands because of reliability and support. Vuugo carries over 30 popular and affordable models of home-office PC such as Acer Aspire; Acer Veriton; Asus Desktop FX series; Asus Essentio and Asus CM series.
