Here are the parts I'm getting: What difference does the cache size on the hard disk make? I'm guessing larger is better. Will that RAM perform well? I was going to buy the 4gb kit before eBuyer put the price back up to £60, I know that novatech have what may be a 4gb kit, however in the title of the item it says "2gb kit (2*2gb)" so I'll just go for the 4 1GB sticks I think. I'm getting the card, processor and DVD drive from novatech as shown here: I googled the card and apparently it's just a re-named version of the palit one. I won't be overclocking the q6600 for a while, however when it begins to need it I'll be fine with buying an after market cooler and OCing it (I'll come back here for some help). No comment on the DVD drive, it seems fairly standard. OS is coming from PC world as an upgrade version for £70 (Win Vista x64) I'll be upgrading from an enterprise edition of XP, however I've read that you can just do a clean install off one. Here are links to all of the parts: http://www.ebuyer.com/product/150283 http://www.ebuyer.com/product/141471 http://www.ebuyer.com/product/127584 http://www.ebuyer.com/product/119279 http://www.ebuyer.com/product/135514 http://www.ebuyer.com/product/103208 http://www.novatech.co.uk/novatech/specpage.html?NOV-4850 http://www.novatech.co.uk/novatech/specpage.html?IL-Q6600E http://www.novatech.co.uk/novatech/specpage.html?SAM-H653B I might set up a raid configuration if that 500gb HDD becomes full, don't think that'll happen any time soon though so I'll only buy a new HDD when needed. I'm just checking that all this would work well together. Thanks in advance.
