Last week I got the best haul ever from Ebay:
A Powermac G4, Compaq DeskPro EP 810, Dell Dimension 2400 and a 17" CRT - all for £0.99!
The auction was just for the G4 and monitor but when I got there, the guy was having a clear out and gave me the others for free (I turned down a couple of printers and a dell CRT.)
Being a local pickup only obviously deterred a lot of buyers but it was only 8 mile from me so no problem.
The G4 is a 450Mhz Sawtooth - it came with a 20Gb HDD, 640Mb RAM, Apple Pro keyboard and is the model that includes a Zip drive.
I wiped the HDD and added an 8Gb Compact Flash card as the boot drive and installed OS9, I also replaced the Rage 128 with a Radeon 9000 Pro (4 times more VRAM.)

The Dell Dimension is a 2.6Ghz Celeron with 40Gb HDD and 512Mb RAM - a fairly uninspiring XP business machine from ten years ago but I did discover someone on Youtube has put together a pack of driver patches that allows it to be rolled back to Windows 98SE, which I've now done - it's crazy to see how fast 98 moves at 2.6Ghz!
The Compaq has a 466Mhz Celeron, a 4Gb HDD and 256Mb RAM - it landed with XP and a headache

I removed the PCI graphics and audio cards - they both appeared to have hardware faults and installed Windows 98SE which now drives the integrated graphics/audio.
I also replaced the temperamental optical drive with a CD-RW and swapped the dead 3.5 floppy with a spare working one.
