actually i thought one of those would look good, sat on a few rubber feet on top of a case or on the desk above a case, fanned up.. £180 is ridiculous, i'm going to speak to some car radiator bespoker/reconditioners, see if i can't get one made up sans graphic for a somewhat cheaper price.
pcs have gone ridiculous now.. seems any decent component is £200 regardless, not good.. i yearn for the days of £25 cpus, £50 mobos.. but £180 for a rad.. stupid
Decent hardware is available at much less than the figures in your post.
In the past couple of years, manufacturers have woken up to the fact that people like pointless stuff which they believe adds value to a given product. As such, we get motherboards costing £300, when previously top-of-the-line hardware costed aroun £130/£140. However, the new motherboards come with copper-plated aluminimum heatsinks, fancy colours, etc. which apparently convince buyers that the hardware is better than something like the Abit IP35 (a little motherboard that overclocks like a demon. For about £50).
It is perfectly possible to build a rig for about £600 that will not perform any differently (perceivably) than a rig that costs £1000. But all the bling associated with 'better' hardware means fewer people seem to be doing that.
The same applies to watercooling hardware. Chances are the Monsta will not be much better (in fact, I seem to remember reading a review of it somewhere which found that it did perform better than a PA120.3, but not £100 better) than a single 120.3 rad, and worse than two of them in series/parallel for 2/3 cost.
But, because it's big, it's expensive, and it comes with funky laser-etched livery, people will buy it under the impression that it is £100 better than the next best thing. Which it won't be.
Heresy! I hear you say. In a forum dedicated to eking out the last drops of performance from a rig, then perhaps, depending on the premise you use for overclocking. Personally, I see it as taking the cheapest hardware and getting the better of the most expensive hardware. Starting with ridiculously expensive kit and going faster is a bit like hot-rodding a McLaren: possible, and no doubt fun, but not quite as good as getting McLaren performance from something lower down the food-chain.
Bottom line? Buy a 120.3 rad and spend the rest on an SSD.
