Xbox 1.1, Chameleon 1.8 w/ X2 4983 bios, Seagate 120GB HDD. Lots of garbage on C and E, but no saves from leaks. Activated XBL after HDD swap in March 2004. Never booted Halo 2 with modchip enabled. Still can play online with no problems.
I don't mind getting banned this Xbox, because then I can flash the tsop with X2 and flash the modchip with debig bios and try some development on it. I have two spare LE boxen - 1.4 Green and 1.6 Crystal, sitting in the closet doing nothing... I don't think I'll ever mod those. May be only after Xbox is phased out, and the only way to play is via XBConnect-like Xbox Link tunneling programs.
