Hello, I’m new to computer building and have based a build on the affordable all rounder from the buyer’s guide. Budget: My budget is £400 for the tower plus mouse and keyboard so I’ve cut down on some areas of the suggested build. Main Uses: My main uses are going to be light gaming (Older games such as the half life series and elder scrolls), essay writing, email, internet browsing and films. Monitor resolution is 1920x1200. Overclocking is a possibility in the future but until I get an aftermarket cooler, no. Current idea for build: Case-------------Coolermaster Elite 335 Motherboard---MSI 770-C45 CPU--------------AMD Athlon X2 245 2.9GHZ Socket AM3 RAM--------------Corsair 2x 2gb 1333MHz DDR3 Graphics---------MSI 9800GT 512MB GDDR3 PSU--------------OCZ Stealth Xtream 500w PSU Storage---------Samsung F3 1tb Optical-----------Samsung TS-H653G DVD-RW SATA – OEM This comes to about £377 which leaves £23 for a mouse and keyboard. My main questions about my changes from the buyers guide are: 1) Is this a decent case? 2) I’ve seen on scan a similar motherboard called the MSI 770-G45. Is it worth spending an extra £6 on this over the C45? 3) Is the graphics card suitable for light gaming on older games? 4) Will the OCZ PSU be a suitable replacement for the corsair from the buyers guide? 5) Will the PC suffer from using the original CPU Cooler? 6) Lastly, can anyone recommend a good Keyboard & Mouse for £20? Thanks for reading, any advice you can offer would be amazing. Cheers .
