£200-250 Budget Everyday Use Build

Hi guys, long time since i've popped onto the Tom's Hardware forums but I come looking for some advice.

I'm embarking on my first build of a custom pc, which in this case is for an everyday use/office based computer for the family. Currently the parts i've settled on are:


CPU:
Intel Pentium Dual Core E5400 2.7GHz 800FSB Socket 775 2MB (2x1MB) L2 Cache Retail Boxed Processor

Motherboard:
Gigabyte GA-G31M-ES2L iG31 Socket 775 onboard VGA 7.1 channel audio mATX Motherboard
http://www.ebuyer.com/product/152225

RAM:
Kingston 2GB 800MHz/PC2-6400 Memory Unbuffered Non-ECC CL6 1.8V
http://www.ebuyer.com/product/148853

GPU: Using On Board graphics

Hard-drive:
Samsung HD103SJ Spinpoint F3 1TB Hard Drive SATAII 7200rpm 32MB Cache
http://www.ebuyer.com/product/173804

Case: Unknown, preferably one with fans and PSU included

OS: Looking to pick up a copy of 32-bit Windows 7


I'm going to be transplanting my old computer's monitor and DVD drive so no need to buy any of those. Really this is just a standard, vanilla build with nothing like Overclocking intended. I'm trying to keep it simple.

Also, I was unsure on the mATX mobo: i'd prefer to buy a full size one but my knowledge of decent motherboards is severely lacking.



Any help or thoughts on this build are much appreciated!
