Custom PCs and Servers

GCS Custom ServersA custom PC is a computer built especially for you. You decide the specifications. How fast, how much memory, type of processor, case, hard drive size, you name it. If you aren’t comfortable with these decisions, we can advise and help you choose the right parts to build the best pc for your needs.

Custom PC vs. Pre-built

  • There are many benefits to ordering a custom built pc over buying one off the shelf. First, and most important, we decide what goes into the pc. This is very important and is usually overlooked in today’s computer market. When you buy a pre-built machine, the computer manufacturer decides what you get as far as hardware. You usually don’t have much say in the configuration. We feel that a pc is a substantial purchase and should be exactly what you want.
