Come to think of it, both my brothers computers are custom built (I built them). Older bro's is a core 2 duo @ 2.4GHz w/ 4GB DDR2 800, nVidia 8500GT 512MB PCI-E x16 GPU, don't remember the motherboard model, I just remember its a 680i chipset on an MSI socket 775 board. 160GB Western Digital SATA300 hard drive, the two DVD burners are shot, they won't burn. They will read discs fine though, its in a black Apevia transformer ATX full tower case.
Both my brothers have the same power supply as I do in my desktop, the RP550 550W rosewill PSU. My younger bro has a P4 Prescott 3.0GHz socket 478 on an MSI VIA chipset based motherboard with an AGP x8 7300GT 512MB GPU, 1GB DDR 400. I don't remember the hard drive size, I think its a 250 or 160GB, though I'm unsure. I know its a seagate SATA150 hard drive. It also has a DVD burner, though I can't remember the speed. My younger bro's system is built in a blue thermal take xaser ATX full tower case. We got it for $40 from a local PC shop used.
My father built his system, he's 57 now, started learning computers about five years ago. He can't name all the parts and he ain't exactly what you'd call a technician, but he knows how to build them. He isn't a complete end user, which saves me a lot of headaches. His system is a 2.93GHz Celeron D w/ 1GB of DDR 400, a off brand PSU, 400 some odd watts (I thought the PSU was gonna blow up, but its braved about two years of use now.), a nVidia 5500 256MB AGP x8 GPU, a 80GB western digital hard drive, a DVD burner, though I can't remember the speed of it either, and its using my first custom system's motherboard, a socket 478 SiS based MSI motherboard. The onboard audio doesn't work, hasn't worked since before I gave it to him. So I gave him the crappy sound card I had, don't remember the brand, or model. My fathers system is in an Antec ATX mid tower case. The case is somewhat fickle to work on, you have to remove the top of the case to remove the side panels. Easier to clean that way though, you can get the dust bunnies around the optical drive and power supply easier. I have large hands like my father, so I need space to work on a PC, especially when cleaning it without tearing it all the way down.
