Dear Mr Tchaikondi,
I am writing to inform you of the research I have undertaken and found. During the past fourteen days I have been researching Computer systems and their components, I have found many interesting things. For the last past two weeks I have found four computers systems and components in which are both suitable and appropriate for your British office.

Out of these four computers I have come to a conclusion based on the facts I have above. I have chosen System four. I have chosen this computer system as it has all the properties needed that is listed and more. It comes with a virus protection programme which is really good seen as children may use the computer. The four computer systems above are all suitable as they are all similar in many ways. System 1 is near enough everything system four is but system four has a lot more to offer, for instance system four had a digital TV tuner, which would be useful to teachers and children. It features wireless network which is a plus due to not having as many leads and wires around.
I have picked this computer mainly due to these features-
2GB DDR2 667MHz memory
500GB SATA hard drive (7200rpm)
256MB NVIDIA® GeForce 8400GS graphics
Built-in wireless (802.11b/g)
Genuine Windows Vista® Home Premium
22” display

System three is close behind system four in my opinion as it has many unique features and functions but the leopard operating system can be very tricky to get used too if you didn’t have that operating system before hand. System two again has many decent features for instance it had a 500 GB hard drive which would be excellent as you can store lots of the computer system.
The total price of computer system four and the Microsoft package totals into

899.99+ 199.00 = 1108.99

This means there is still money left for components and extras. The total amount of money left over will be

2500- 1108.99= 1391.01
