Ok, adding another fan shouldn't be a problem, as for space issues I'll just have to see and possibly look into a slightly larger tower, possibly one of the smaller HAFs

Ok so I'm upgrading my PC and I've started to worry about whether or not my current case is good enough. The case is a Cooler Master Centurian 5with two fans(the old one not the centurian 5 ii).

This is my current setup:

• XFX 8800GTS
• Intel Core2 6420
• 2GB RAM
• 300+GB HDD

I plan to upgrade to:

• Dual EVGA GTX 570 in SLI
• Intel Core i7 2600
• 8GB RAM
• 1.5TB HDD

I don't plan on overclocking anything, andthe room is never too hot.

Will the Centurian be able to keep this setup cool? If not whattower should I look at?(no full towers, it must be a mid tower or else it won't fit under my desk).

I'm also considering possibly adding an extra fan on the side of the centurian in order to improve air flow - will this help or is it unnecessary/not good enough?

I'd love to get the mamba but price is the only thing holding me back, besides the wireless functionality I just can't see any other benefit.

I'm not really a big fan of the R.A.T, I think it looks like it will start falling apart in about 3-5 years.

So far i'm thinking Lachesis or perhaps Mamba if I buy it on impulse

Ok so I'm soon going to be upgrading my PC and I figured I might aswell go for a new mouse and keyboard whilst I'm at it.

However I can't decide between the Razer Lachesis (the newer 5600dpi not the old one) and the Razer Imperator. According to the Razer website they both cost about the same and I'm really not sure which one is the better gaming mouse.

Could anybody point out the differences between these two and give some advice on which is better? If it helps I currently use a Razer Copperhead and I love it so ideally I'd like the replacement to have a similar feel (size, weight, shape, etc...).
