Computers can assemble your custom build. I no longer design systems, but I am happy to expertly and neatly build your dream machine.
Labor to assemble gaming machines will vary depending on complexity. For example, builds with lots of RGB fans can add a fair amount of time to wire them. I prefer to install the OS also, to make sure the hardware works as expected. Labor is typically 1.5-2.5 hours, but especially wild builds have exceeded 3 hours in the past.
I try to keep some refurbished business-class machines on hand for solid performing, non-gaming use.
New laptops are not something I can offer you. Refurbished business-class machines are on hand when possible. COVID has made finding acceptable deals on them tough.
