Intel LGA775 Core 2 Quad 21.4GHz CPU with OEM HSF.
Giga-Byte GA-X48 DQ6 motherboard
8GB (4 x 2GB) Corsair CMX2048-6400CS
Latterly, I've been running this setup at stock speeds but it has been known to run at eye-watering speeds when overclocked. The Corsair memory was apparently designed with overclocking in mind.
Anybody want the lot for Ã‚Â£100?
