I'm looking at replacing my current behemoth of a gaming rig with something distinctly smaller, yet still able to do some serious gaming. Here's what I have so far: Uploaded with ImageShack.us Comes to just just shy of £1650 with VAT. Some concerns I have: The Bitfenix site says that the Prodigy's PSU case is 180mm in length, but to give cable clearance you should a PSU of 160mm length maximum. Hence the Silverstone PSU in question. But I've heard that is incorrect and actually you can only have a 140mm long PSU with cable clearance. Which is correct? I'm going with 8GB of RAM - but should I go with 16GB straight away? Will that kind of raw power be needed in the next couple of years? As far as cooling goes, the plan is to mount the Antec 920 in the roof - will I have enough space for the optical drive? Furthermore, will the Antec 920 in the roof leave enough room for a 25mm thick fan at the back of the case? Finally, I plan to run 3 x 120mm PWM fans off the Akasa cable and CPU fan connector on the motherboard, the pump for the 920 from the system fan connector on the motherboard and the 230mm fan via a PSU molex cable. Any thoughts?
