Prophet, I'm looking to get a new custom build computer, however, I'm afraid that the costs locally to build one will be well out of my affordability range for a long while, what I'm looking for is a way to build a computer essentially a piece at a time as I can usually only spend about 100 to 200 bux a month extra to put out towards something...I don't know, would it be safer to go the localized route and do it as I can afford components? Or would it be better to go through you. I'm only asking because I'm not really sure about anything computer related actually.
