First of all: postage. Surprisingly, CCL's 5-7 day option came the next day which i was very pleased about, and the amazon followed the day after, however my purchases from dabs.com didn't arrive for ages! It was slightly my fault but very disappointing from dabs. I put in the order on 17th of Dec and they were only dispatched on Jan the 8th! I knew that the were 'On Order' but I wasn't expecting them to take so long to restock. Their customer services were useful but they had so many days off after Christmas and so it turned out to be a very long wait. Thumbs down to dabs and whoever stocks their Corsair power supplies.
Now that I've built it, it works pretty well. The components all do their job, i only notice the occasional hiccup. The case wasn't on pcpartpicker, but i didn't like the selection they had so I went on Google and found this. My network card's metal plate doesn't reach the gap for it at the back like my GPU does, but it still sits in it's slot and works fine so there's no problem. Also the slots aren't the typical unscrew and slide out. You have to bend them and snap them off, which isn't difficult but would make it a pain to return or resell the case as it is permanently gone. Also, of the three USB 2.0's on my case, i only plugged in two, yet all three work :S I also don't know which cable the card reader connects through either, but i think it works fine. Slightly confusing but there's no problem.
The biggest problems i have had are weird game experiences. I think it's something to do with how i built it, maybe i plugged something in loosely. Earlier today i was in a game of Gmod murder and the screen went black and played some weird sounds, so i had to reboot and now it is fine.
The only other problem I had was my keyboard and mouse. The first mistake I made was getting a cheap wireless one, which isn't good for gaming and was never going to last long. The keys were unresponsive and i returned it, so to replace it i got a CoolerMaster Storm Xornet mouse and a Zalman ZM-K-400G Keyboard. The mouse was cheap and has nice ergonomics, the keyboard was also cheap in relation to other gaming keyboards as it was £30 and most are £60-£80. It isn't the best but it has some programmable keys and blue/red LEDS which go with my colour scheme. The webcam by the way is a Microsoft Lifecam HD-3000 which was about £15, but i didn't want to waste money on an ugly, bad quality one. It does the job fine, and it's a similar story for my headset which is a plantronics gamecom 380.
