Q: I was thinking of changing my case thing of it to this: http://www.aria.co.uk/Products/Components/Cases/MIDI Tower/XClio A380 SuperTower Silver Window 25cm & 36cm Fans ?productId=32404 Can I?
A: Not a problem, as it's an ATX case. If you haven't yet, you'll need to upgrade the stock power supply, though. 250watts of power isn't enough to power the more massive fans, along with the other hardware (120mm fans can take 5watts to itself, the massive one even more, compare to 1/1.5watts for a 80mm). Get no less than a 600watt PSU now, and a good one is Seasonic SS-600HT (it works in P4 systems, and has both SATA and Molex plugs, with short wiring that fits just right in a mid-sized SOHO case). So whenever you upgrade, you can still use the PSU later.
