Looking to buy a new Hard Drive? I would recommend getting a 500GB Western Digital from eBuyer. The drive is dead fast and has masses of space. I recently bought one to replace a very noisy Maxtor 250GB which I now have as a slave.
If you need a fast, large in GB's and a cool quiet drive go for a Western Digital 500GB SATA drive. You can find it
here on eBuyer

By the way, make sure that your motherboard has a SATA I or SATA II port, otherwise you won't be able to use this drive!!
