Hi all.
I'm going to take the plunge and do a serious upgrade on my computer.  The problem is, I don't know if all the items are compatible with one another.  Here are the specs :

Mobo:       MSI K7N2 Delta-L SKT A 8xAGP DDR400 Nforce2 6ch Sound LAN USB 2.0

Proc:       AMD ATHLON XP2700+ 333MHZ FSB 256Cache CPU - Thoroughbred - OEM

Video:      XFX Geforce MX440 AGP8x 64MB DDR TV-Out Retail Box

Case+psu:   eBuyer KG-888-B 400watt Atx Case In Blue With Front USB/Audio/1394

All of these items are from E-Buyer and it all comes to (including VAT + Postage) £165. I have a £200 budget.

The CPU heatsink and cooler is from Quietpc.com and is a Nexus AXP-3200 AMD Copper Plated Cooler at £22.
 
Hard Drive: I already have a Maxtor Diamondmax 120gb 8meg cache (IDE 133)

Ram:        I already have 512 Mb of PC2100 DDR

Optical drives are a Pioneer 106D DVD writer and a Sony DVD-Rom drive.

I have all cables and fans (including floppy drive)

Any advice on the above would be greatly appreciated.
Many thanks in advance
