Im looking to build an ultra low profile desktop, for which i will be building a custom case. so far i have found all the parts that i am looking for except for a power supply that can carry 350W but is no larger then 3". I am completely open to the idea of custom working a power supply, but i have no background in it. I have no time frame that i am working with so i have time to learn and mess up as well. Another option that i am looking into is using an external power supply, but again i cant find anything that puts out enough power. Im open to suggestions!
