The great thing about a custom computer is just about anything can be changed to suit your needs and preference.
For example:
The case's colour, shape, size, and style can be changed
The memory can be expanded for running more apps at once
The processor can be scaled up (or down) to suit you performance needs and budget.
Storage can be increased for more space, or changed to a solid state drive for more speed
The display can be a 28" 4K or a 22" to save space and money
And so on.
Over the last few weeks we've had many requests to offer different motherboards in our systems, different cases, more videos cards, etc. The nice thing about being a small business is we can quickly respond to many customer requests and actually make those changes — which keeps everyone happy. On that note please look forward to the extra options we will be adding this week!
