Budget PC case
Any cheap ATX case will do for your computer. Working inside an ATX case is pretty easy as they are really roomy as compared to a mini-ATX or Small Form Factor computer case. Your case should include a power supply of at least 300 Watts. This is the power that will run all the components inside your computer case and also some of the peripheral accessories you may choose to plug in via USB. A mid-tower size case should provide plenty of airflow and room for future upgrades for a basic computer.
If you’re looking to combine style and functionality check out Antec’s SLK2600 AMB (B00006HYNZ). Antec is one of the largest manufacturers of computer cases and delivers a quality product. The special door on the front of the case will block some of the noise that open-face cases would leak out. It also includes Antec’s own 300W SmartPower series power supply which delivers rock solid power to your components.
