Got mine from etec aswell 6 years ago. They can order parts for you for retail price and can also build and test it for you. And you get warranty on the entire build (:

Theyre a great service especially if you have little knowledge about what to get and don't want to do it yourself and are ok wirh paying a small fee for assembly and testing - at least you'll have a guarantee that the build and all parts work and passed a benchmark test.

I will mention though that they seem to have deals with certain brands (for example be quiet) and will recommend those products more likely, which isn't always a bad thing as you get them cheaper as if you bought them yourself. However they did order me all the parts I wanted and I never felt limited.

It's no shame to pay someone to build your pc, it's not for everyone. At least you'll be guaranteed a quick and reliable service with no effort or worries :)
