I chose to go with a prebuilt since I wanted the peace of mind in case I needed support, and it immediately paid off. The original PC I ordered had a fault and Andromeda went above and beyond with their customer service in addressing it. They responded within an hour of sending a support email and after some troubleshooting, were kind enough to immediately offer a replacement and even went as far to throw in a free upgrade. Even though it was during Thanksgiving week, they still overnighted it free of charge and it arrived in 2 days. The tech I spoke to, Trung, was knowledgable, professional and easy to speak with. I was expecting a fight to get a replacement but it was painless and prompt.
The replacement unit works flawlessly and is the nicest PC I've ever had. I have no doubt that it will last me another 10-15 years.
A big box retailer will not give you this level of service or care. They've made a customer for life and I'll be recommending AI to anyone I know when they look to upgrade.
