In my continuing quest to emulate the legend that is Bat69, I've just treated myself to one of these very wonderful PC cases.
Linky thingy.
On the downside, it comes with only one fan fitted (in the lid of the case), but adding others to the front and back was an absolute doddle - I've used 120mm Hiper chrome ones with blue LEDs, which make it look the puppy's plums. Also, it's rather larger and heavier that I probably would have liked, with the result that it dwarfs yer average garden shed and requires a forklift truck to move when fully populated with gubbins.
On the 'plus' side, it runs cooler than a snowman with a kipper tie and is ridiculously easy to work on. Oh yes, and it only cost an insanely piffling £49.99 plus 12 quid P&P. Because I bought the fans and a keyboard from the same dealer they were also included with the carriage charge.
Buy one now while the going's good. Go on, you know you want one. Just do it.
