Scan are possibly the worst company I have ever used! I stopped using them last year but previously had bought most of my PC parts from them.
Everytime there was some sort of problem:
1. The order hadn't been picked(forgotten to)
2. Delivered the wrong parts
3. Delivered an Athlon 900 and said it was a 1200mhz
4. Took over a month to test a CPU before telling me that "It's ok it's only chipped a bit on the core". It wasn't chipped when I sent it to them!
I ended up threatening them with watchdog TV program before I had an apology from the 2 guys who own it.
NEVER, NEVER, NEVER, NEVER use them
OK, rant over
