Does this look trustworthy ?

If you mean 'Trustworthy' by the manufacturer then BEDIR SHOP is kinda thin on the number of reviewers - http://www.amazon.co.uk/gp/aag/main?ie=UTF8&sshmPath=at-a-glance&isAmazonFulfilled=&marketplaceID=A1F83G8C2ARO7P&isCBA=&orderID=&asin=&seller=A1ZTMS7CNB7K7Q&isPopup=

I would recommend CyberPower - http://www.amazon.co.uk/gp/aag/main?ie=UTF8&sshmPath=at-a-glance&isAmazonFulfilled=&marketplaceID=A1F83G8C2ARO7P&isCBA=&orderID=&asin=&seller=A2V4HKR69F1Q48&isPopup= they've been in business for quite a while longer. At least they're listed and I know of them and their business practices which are good - http://en.wikipedia.org/wiki/List_of_computer_system_manufacturers
