Heres my setup.
I got the Dell for free yesterday from the non-profit I donate time to. Its a Pentium4 HT 2.8 GHz, with 512MB of RAM and an 80GB HDD, as well as a DVD-ROM. We got over 270 of them from the community college (we refurbish machines and give them away to schools). Everyone got one, since we all pitched in and moved all these machines. I took it, dropped a gig of RAM into it, a AGP FX5200, and a CD-RW drive.
My Quicksilver G4 is a Dual 1 GHz G4 box, with 1.5 GB of SDRAM and a Radeon 9000 Pro card, with a 40 GB drive, and a 30GB hard disk drive, and it has the original 2X Pioneer Superdrive, and the Zip 250 drive.
The Quicksilver is the white monitor, the Dell is the black.
