Hi all, I have an Acer Aspire RC500, It has a very small 120GB IDE hard drive, I would like to install a 500GB or 640GB sata HDD, I brought a 2 in 1 IDE to sata converter a while ago and it doesn't quite fit, I am now looking at this item http://item.mobileweb.ebay.com.au/viewitem?itemId=300792882660&index=14&nav=SEARCH&nid=33963272739. Will this work for what I want, If not please tell me what I would be needing.
