So,
my retro pc isn't powering on anymore and I don't really care enough to try to fix it (i suspect it's the power supply unit that's busted).

If anyone here is interested in any of these parts I can send them to you for free, you just need to pay for shipment from Germany (or come pick them up in Berlin if you're around):

• Chaintech 5RSA2 motherboard (super socket 7, 1xAGP, 2xPCi, 2xISA)
  AMD K6 @ 300mhz
  AGP Matrox Millenium II w. 4mb ram
  256mb sdram stick(i think? might be 128mb)
  4gb compactflash with IDE adapter (so it can be used as a HDD replacement)
  some random seagate HDD (sorry don't remember the capacity)
  CD-RW drive (20x10x40)

As I said I don't know which of these if any is busted - I have no other computer from that era to test them & this one isn't even powering on. But I would guess most or all of them are functional.

Send me a PM if interested.
