I own the following machines, installed the following distros:
Primary home desktop - cpu=2.4Ghz Celeron, ram=640MB, distro=PCLinuxOS 2007 (not my first choice for myself, but MEPIS had issues with video card) WAS WinXP-home.
Secondary (basement) desktop - cpu=P3/500, ram=192MB, distro=Zenwalk 5.0 WAS Win98 and a variety of other distros. My test box.
Laptop - Compaq Presario V2000, cpu=AMD1300+, ram=384MB, Dual boot WinXP-pro/SimplyMEPIS 7.0 (my #1 distro choice)
Work Desktop - Dell L933r, cpu=P3/933, ram=128, distro=SAM Linux (a PCLOS remaster using XFCE) WAS WinME
Machines I volunteer to admin for a local coffeeshop:
One - IBM Netvista 6841, cpu=P3/1000, ram=384MB, distro=PCLinuxOS 2007 (my #1 choice for newbies and general public use) WAS Win2k
Two - generic P3/1000, ram=384, Win2k (haven't brought myself to convert it yet)
Three - Dell Optiplex GX1/500S, cpu=P3/500, ram=128MB, distro=SAM Linux WAS WinXP and slow as hell, now keeps up easily with Two.
