yah its the standard atx p4 3.0ghz i have 1.5gb of ram , thanx for the response but i believe i found one. the Ultra LS350 Lifetime Series 350W Power Supply - ATX, SATA-Ready, PCI-Express. has the voltage in the right places. talked to some people and they headed me in this direction. its very hard trieng to find the right one as i have found out in the last 4-5 days. the case can only handle a 6" wide by 3 3/8 vertical and 5-6" in length power supply.
