Mine went swimmingly, apart from the bit they left out and the bit they gave me duff info about. But the first was sorted pretty much instantly- they refunded me not what I paid, but the full value of the soundcard, which meant I came away ahead on it... Very impressed with that. And the second (only one PCI-E slot) they're looking into now.
Delivery was smooth and fast, 5 days despite my oddball spec (I took a rubbish 5150 and upgraded it to abuse some deals) although I did get the same thing with it not showing in their tracking system at all.
Their telesales people are an absolute joke- but here's a hint. When you get a price, it's not final. The sales guys are all dying to give away parts of their commission, and frankly they're so incompetent you can't feel bad about taking their money
I played 2 of them off against each other and got £75 off an already storming deal- just refused to close the deal on them. "I'll call back later" "I can offer you this right now" "I've already got a better offer from one of your other salesmen. Beat that, and it's yours" It's a ridiculous situation, you owe it to yourself to take advantage.
Most important though, there was nobody else that could meet their spec without being at least £200 more expensive- on a £600 machine, that's immense. Had to take some wee compromises on spec and upgrade after, but that's OK. The graphics cards they put in the lower end machines are utter rubbish, by the way, and the hard drive upgrades are just ridiculously expensive.
