Whoa, a lotta good replies here!
Well, I added on the Antec 430W power supply, and the arctic silver thermal compound. I think I'm good to go now, I will probably end up ordering the setup late next week. I'll add round cables and the cathodes at a later date when I have some more money. I still need to buy an LCD monitor, but until then, I have a 2 year old sony crt flat screen to use. Feel free to add any suggestions until then!
When taking the 420W power supply out of the case, will the Antec go in with no problems?
