both builds look great, but the case and cooler in the second one are much better. however, if you prefer the looks of the HAF X then go for it. i'd far rather you had a case you liked the looks of but was slightly worse than go for something you dont like the look of bu is slightly better.
as for the waiting game your totally right, you wait for some piece of new tech and then something else is on the horizon. the main reason i was saying to wait is because it sounded like you werent going to be able to get the money together for a while anyway which meant it was pointless recommending you something now as the new stuff might have been a lot better for the money, we just dont know.
if you have the money now then the only thing that might be worth waiting for is bulldozer, as its looking like that will be coming very soon (september 19th). however, whatever you buy now will still be good because its not as though with the release of a new processor everyone in the world is going to buy it making every single game run terribly on the old stuff, so whatever you buy now will still be good for a number of years. also, going by AMD's past record bulldozer
probably wont match the sandybridge processors anyway
if you give me a budget to work with i'll see what you can get for it
*edit*
as for the other bits all the PSU's look very good. you cant get the seasonic from OcUK so it might mean a second delivery cost for you, but other than that its impossible to say anything bad about it because its a seasonic
the GPU i wouldnt go for because if you look at it closely you will see that it takes up three expansion slots on the motherboard. this means it will have very little breathing space if you add a second one in SLI as the fans will be pressed against the second card. it will also mean you wont be able to add much else in way of expansion cards as all bar one of the slots will be covered by the giant coolers.
there is nothing wrong with the motherboard (its a common recommendation on OcUK) but it is also not as good as the MSI one i have recommended because the motherboard supports PCIe Gen3 (when you have an ivybridge processor in it. this gives you another upgrade option later down the line. if you really dont want the MSI one ive recommended then go for the Asrock Z68 extreme 4 Gen 3. the only reason i didnt recommend that instead is because its £10 more then the MSI and i really cant work out why (it was the same price as the MSI a while ago but OcUK have upped the price for some reason)
hope that helps
