Metaversa 01 has been a good workhorse, able to keep up with the best of current machines, but in some respects it is showing its age. It is time to start thinking of a new build... and a new modding project. My inspiration has been anything from Confederate Motorcycles to antique microscopes, to Babbage's Difference Engine to anything that is Victorian scientific engineering. 'Cause I like the look of Steampunk, see? Another inspiration has been my passively cooled HTPC. There is something really cool (pardon the pun) about switching on a PC and hearing... nothing. Just a power LED and some subtle chittering of the hard disk to indicate its heart beat. Silence is golden, so I have been wondering if it is possible to design a capable system around the Alphacool Cape Cora passive radiator system. Tricky, because a decent array is huge and would dominate the design of the case. The problem has been to design something that works (obviously), looks fairly elegant and can be fairly easily manufactured from brass and aluminium. This is not as easy as it seems... some rules have to be obeyed. The reservoir needs to be at the highest point in the loop, the pump as low as possible. Weight distribution needs to be even --a beefy PSU weighs about 2kg at least, but so does a Cape Cora radiator filled with 2+ litres of fluid. Another consideration was that I want to get away from the same old square box. Problem is: most PC components are designed to fit in square boxes. Not only that, but in specific locations and orientations in those square boxes. You see the problem... The most important consideration is: aesthetics. Metaversa 01 was a long time ago, when 12V pumps for PC watercooling did not yet exist (I improvised with a car booster pump) and, well, my humble attempts with aluminium shrouds and GPU support brackets still impressed. The project logs I see on Bit-Tech nowadays blow my old mod clean out of the water. Modding has become a lot more sophisticated and the quality of the work has been raised sky-high... I would have to pull something mega-awesome out of the hat to compete... With that in mind, this is what I came up with messing about in SketchUp so far... Design 1: Nice idea, but no good spot for the reservoir. Weight distribution would also be uneven. Design 2: I like this one, but it would be huge. The pump is in the bottom of the reservoir. The HDDs at the back of the mobo have a clever self-clamping mechanism. However it is getting a bit complicated to build... Design 3: Inspired by Carlo Bugatti's furniture (seriously, have a look at his stuff!). The mobo tray (not modelled here) would tilt forward on a big circular hinge (which at the back houses the pump, at the front would house the panel with power button, indicators etc.) to allow access to the connectors at the top. Still, not quite what I was looking for. Design 4: This is the current state of play... Metaversa 02 Cathedral "Camille". I quite like this design but although most parts consist of simple aluminium tubing (with some brass milled collars) and flat laser-cut aluminium parts, there are a few parts that would need CNC'ing, particularly the curved legs, the reservoir clamps at the top and the brass reservoir end caps. Not something I could do myself, and I can see the manufacturing costs mount... still, I may explore this idea a bit further. What do y'all think? Would it work? Would it not work? Is it just plain ugly? Those of you who have l33t CNC and milling/lathing skills, do you spot anything that would be a nightmare (or very expensive) to produce? Your thoughts and considerations are eagerly solicited.
