Hello, need some advice on building a new system in the UK

Hey there,

So I am planning to build myself a new system. Figured I'd learna thing or two about components and save myself some copper in the process.

I'd like to start out slowly and basically upgrade my existing systme and eventually upgrade all my existing components.

So without further ado:

APPROXIMATE PURCHASE DATE: Within 2-3 Months
BUDGET RANGE: As Cheap As Possible, lets say 400-500 Bucks (only need several components)
SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming, watching movies, image/photoshop editing.
PARTS NOT REQUIRED: SEE BELOW
PARTS REQUIRED: Case (would need a big one so I wont have problems upgrading ion the future. One with sufficient space for airflow etc as I have currently overheating problems), Motherboard (would also like to get quite a good high performance one, with DDR3 if possible, would like for future upgrades), GPU, perhaps more

PREFERRED WEBSITE(S) FOR PARTS: REPUTABLE UK Websites? I guess scan.co.uk ebuyer.co.uk, not sure though COUNTRY OF ORIGIN: England (UK)

PARTS PREFERENCES: No Preference, whatever works with what I got

OVERCLOCKING: Might Install DUela Graphics cards in the future

MONITOR RESOLUTION:1600x1200, 1920x1200)

ADDITIONAL COMMENTS: I dont care about the noise as long as it doesnt take the piss, aka, not like a neumatic drill.




CURRENT SYSTEM: from which I would like to necro parts onto the new system and eventually upgrade them out.

CPU: DualCore Intel Core 2 Duo E6300, 1866 MHz (7 x 267)

Motherboard (would like to replace, probably real junk, or maybe its any good? tell me!): 01/30/2007-LakePort-Leonite-00 NAME: Asus Leonite
Chipset: N Bridge. Intel Lakeport-G i945G


GPU: PCI-E (ATI Radeon HD 3600 Series [1002-9598] [NoDB] 512MB, High Definition Audio Controller [1002-AA20] [NoDB])
Soundcard? Realtek ALC888 @ Intel 82801GB ICH7 - High Definition Audio Controller [A-1] PCI



Allright, so basically I have a harddrive, a DvDRW and all that Jazz. I am just interested in replacing the core essentials of my system to keep up with the higher graphics demand. SO I guess I would like to upgrade my GPU< but as far as I know I cant do that without upgrading ym Motherboard and PSU.

Another thing to note,m my current tower pretty much sucks ass, because the way its positioned, the PCI-E slot is right off the bottom of the tower so I cant put in any good GPU's even if I wanted to because 1. of the crappy motherboard layout it will prevent any good GPU fan. And 2. because insufficient space between bottom of case and my GPU.
