Is the corsair bulldog a good value?
That depends on what scale you're measuring it.
An SFF water cooler to me entirely misses the point. If you want small then buy appropriate hardware, don't try and contort big hardware to fit into a small case or you end up with something like this - which, to me, is over-sized and over-complicated.
We can help advise on the trade-offs between hardware choices and how close a given bit of hardware comes to fulfilling criteria but only you can decide which aspects of hardware are important to you.
What do you want from a computer? Are looks important? Is water cooling attractive for it's own sake? Is size an issue?
