It died on me :( looking for advice on new kit

[Lozza]

So my vintage 2007 htpc has died on me

Switch it on and the psu works and the light on the power button works... It was going through a cycle of restarting but not even that now... no beep no post from the mobo, so assuming it has died.

I lost a lot of blood sweat and tears on that baby...

I should like to keep the case so i'm looking for the internals,.. previous vintage was:
Gigabyte GA-G33M-DS2R
E2140
4GB (4x1gb) Geil PC2 6400

Way out of the loop these days... so Dym posted this And Leo posted this but the currys version.

Which would I be better going for?... I have a little concern for the OCUK bundle in that if I wanted to add an extra 4gb ram ...

Please note that adding in additional memory to the spare slots will require new BIOS settings and the maximum clock speed attainable may be significantly reduced. OcUK recommend a quality brand PSU for use with all our bundles such as the Corsair TX & HX range. Updating the BIOS on the overclocked bundle range will void the warranty on the overclock. If you update the BIOS we will no longer be able to provide support for configuring and maintaining the CPU overclock.

Or indeed any other bargain bundles/componants out there?
