Changes

<td>Hard Disk Size: at least '''160GB'''.<br />'''Please buy the tray from ACS or the bookstore''' as not all trays are compatible.<br />Please do not install the screws for the hard disk tray as it might become loose during usage and cause your hard disk to become stuck. Note: Hard drives are currently expensive due to flooding in Thailand. Solid state disks (SSDs) are becoming competitive in price, are faster, and are less susceptible to shock, so you may want to look for a deal on an SSD instead of a hard drive. If you use a mechanical hard drive, be careful not to drop it, and transport it in a padded container (e.g., a neoprene netbook sleeve, available from some dollar stores).</td>
