I have about a 400$ dollar budget at most and have put together a parts list and I was wondering if I was making any mistakes and if possible I would like to minimize the price. i do need the OS included in the price but I could take out the case and put in a power supply instead because I own a Dell dimension 8400 which I can get the case from.
