Just replaced my ageing Antec 900 with the CM Sniper. It is brilliant!

£5 more than your budget (though it can be had for under £100).
The cooling as standard is 3x200mm (intake, roof, side-panel) + 1x120mm (exhaust) + 1x optional floor 140/120mm fan , so if you are looking for coolling performance you wouldn't be disappointed. Plus there is a built in fan controller (for up to 5 fans). All intake fans are filtered.
My observations are that it isn't as "gamey" as the name or photos imply (much less so than the HAFs IMHO). The LEDs can be turned off by a switch integrated in the fan controller. With the fans turned down it is quiet. It is larger than it looks. There's scads of space to put whatever you like in it. My 5870 fitted in absolutely no problems. Build quality is very good as far as I can tell. Due to the verticla bulge of the case sides there is also plenty of spave behind the mobo for cable management. The thick psu power cords going behind the board easily.
Not going to be a fanboy about it but I'm more than happy to recommend it.
My vote.
