I recently obtained a secondhand Powermac G5 1.8Ghz Single-core CPU w/ 1Gb of Memory and a GeForce FX5200 (ADC & DVI) gfx card [this model: http://www.everymac.com/systems/apple/powermac_g5/stats/powermac_g5_1.8.html] I was wondering some recommendations to help keep its usefulness up and maintain it for quite awhile and also wanted to know if anyone knew of any good place to find the following peripherals: 1) Memory; I was curious if this basic PC3200 memory would be compatible: http://www.newegg.com/Product/Product.aspx?Item=N82E16820161161 2)Video Card; any pace to find a decently priced (less than $100) for a gfx card that can support resolutions higher than 1920x1200? The FX5200 can barely support upto that. 3) A nice IR Sensor; I have Leopard + an Apple Remote and I wanted to turn this into a nice media server (generic appletv like setup) 4) A decent external DVD drive that can be hooked up via USB or FireWire to use with FrontRow DVD playback. 5) Sata 3Gbps HDD; I have some spare SATA 3Gbps (SATA-II) drives im wondering those would be capable of running in a Powermac G5? Im assuming all I have to do is set the pin to allow the 1.5Gbps connection...other than that larger drives than 500Gb should be recognized? Or any other thoughts and recommendations. thanks alot!
