Yep, after about 6 months of research I finally decided to order the parts and just get it done.  
This was the first PC I ever built and I was quite surprised how easy it was. I pretty much learned everything I needed to know from Geno's thread and Tested's How to video. The only problem I ran into was installing the OS as I installed the 32 bit version of widows instead of the 64 bit.  
 

The Good

• Its damn fast, the fastest PC I've ever used in fact.
• Its nice to finally be able to play PC games without them looking like slide shows.
• I finally have a place to store all my data that isn't an external drive

The Bad

• MSI includes a special technology on their motherboards called O.C Genie which is meant to take a measure of your system and automatically overclock your CPU and memory, this automatically gives me a BSoD so I'm going to have to learn to overclock for reals.
• I order all my parts from Germany as the prices in Ireland for PC parts are ridiculous, part of this order was a keyboard and to my surprise it was in German (facepalm). So all the basic keys are the same i.e A-Z, 1-0 (had to switch the y and z keys around) but the symbols and function keys are all fucked up.
