I cannot say this enough, I wouldn't buy something from scan if you paid me to.
I had the misfortune of building a machine with parts from there once, this is what went wrong
Motherboard - wrong one in box.They decided to try to charge me for a new one, until I pointed out the receipt was for the correct one.
Monitor - TFT panel - more dead pixels than live ones - they again accused me of damaging it.
Floppy Drive - didn't work
DVD Writer - wouldn't even light up
Hard Drive - blew a chip as soon as it was connected to power - they took over 6 months to replace this one.
Processor - faulty
Ram - faulty, 3 times, and they wouldn't switch it to a different brand after the third time, or give me a refund.
Essentially, I have never been so disgusted with the quality of parts, or after sales service of a company, I will NEVER shop there again, Even NTL are better than Scam.
I switched to shopping at spoton, and have spent about £8000 on computer bits from there. They have only supplied me with 2 dodgy items, 1 was a DVD drive, which they changed on the spot, no problems, the other was a CPU fan which had a noisey bearing, again, swapped on the spot, no problems.
My recommendation -
Spoton Computers
