You need to consider is the size of your business and whether you're looking to grow. If your business is small, you can probably get by with commodity hardware generally available at any computer store. But if you're looking to scale up, or your needs are more specialized, it's worth buying custom-built servers that can handle high-performance computing (HPC) applications. In addition to asking others for their opinions on specific brands, you can also research online to see what other companies are using. Before buying any hardware, make sure it supports all of your business's software programs. If possible, opt for a PC with an integrated graphics card because many business software applications require one to run correctly. While these aren't technically part of your computer's hardware, they're still vital pieces of gear that should be considered when building out new computers for your office environment.
