a quicksilver dual 1ghz G4 tower. It'll survived longer than my G5 Quad will since the G5 is having thermal runaway issues...
Mine is now with my aunt. It's a Blue & white G3 with a G4 500MHz, 1GB RAM, 40+30GB HD and a Radeon 7000 32MB. Also added a USB 2.0 PCI card for her camera and replaced both stock fans with high end Antec dual ball bearing. It's painted like the one in my signature but with spray paint rather than car paint.
I set it up for her with 10.4.11, office 2004 and iphoto 08. She is very content with the performance as all she does is web, personal photos and use word.
Forgot to add that I bought this B&W new in 99. Had it ever since and it still runs 100% great.
