    I saw the reviews for it maybe a year ago - really seems like an excellently designed block with incredibly fine and fantastically machined channels (they're so uniform I presume they're CNC machined with a slot disc rather than skived) - 0.15mm wide fins with 0.2mm thick channels, and the acceleration nozzle aimed at the CCX/cores to optimize turbulence there. Can see why it came top in testing by a decent margin, though restrictive as a result of the design.

    Totally agree, the machining is made with "scrupulous attention to detail" (I quote them :grin: ) and I believe so when it's manufactured in Germany, those guys are serious...EK certainly offers some high end coolers as well, but I found, in addition to their efficiency, that the overall design of TechN coolers is much more beautiful... :naughty:
    BTW, may be you visited it already, but if not, they have other wonderful items on their site, I like their pumps a lot too...:grin:

    I would think that the design wouldn't be that restrictive, considering the dimention of the case, it seems to me that the free space for air circulation is enough for a good heat dissipation :worried:

    Yes I saw their DDC pumps - very nice design (though I'd prefer a clear top with a surrounding hidden band of LEDs behind aluminium housing). I'm going for D5 this time round for noise reasons - in the past I found the 18w ddc noisy and even the 10w DDC was only really quiet at very low voltage.

    Update

    Tidied up the alternative orientation PSU hole with some dremelling/filing and sanding. Cut and installed some rubber spacer strip between the aluminium angle legs and the veneered backwall, and drilled/countersunk 8 more holes to the aluminium angle legs, to give more structural rigidity and some vibration dampening. Made things shiny.

    Here's the backwall/frame, with the 'alternative PSU orientation' hole open.

    Really must break out the full-frame DSLR and take some better pics as my phone camera really struggles in low light and smears detail with aggressive noise reduction!

    Thanks for reading.

    Brrrrraaakkkk! Turkey getting stuffed, and merry Christmas!

    Been a bit snowed under with flu and family things.

    Gave the walnut-veneered wall 2 coats of the finishing oil (tung/polyurethane mix mainly). Got an EK FLT80 reservoir and gold-plated D5 bottom. Probably going to live like in the video below as gives a super short loop. Very shiny! Replaced some of the countersunk black screws with GR5 titanium ones. Made a temporary polystyrene block to hold up to pump (need to make a vibration-dampened bracket). Soft tubing doesn't like any bend radius with an unsecured pump, hence the pump being at a funny angle in the vid.

    Hammered in the 14mm pipe bender pivot pin (it was misaligned by about 2mm for the two halves with the pipe grooves. I hammered through by perhaps 2mm with a centre punch chisel, and inserted two external 8mm circlips as spacers for tge pivot pin. Seems to be about right from eyeballing. The polished and lacquered copper hard-tubing with the golden corsair (bitspower) fittings will be added later.

    Something of a temporary loop atm - need to check the GTX 4090 works fine aircooled before putting the block on and redoing the loop, so just the CPU in the loop currently. Doesn't leak!

    Got a Bitspower vertical GPU bracket.

    https://shop.bitspower.com/index.php?route=product/product&product_id=7012

    It can have two cards vertical, and it's modular so you can remove half when one one card is in use. It's CNCed and looks very nice, though it's black (I think anodised rather than powder-coated). May well be fine as the motherboard is black and looks pretty good installed, but need to see what it's like when the cards in place.

    Anyhow, here's a vid. Will post more photos for the bits I described, but it's 10:51pm and I wanted to make the xmas turkey pun and fighting against the cluck a bit here. Merry Christmas all!

    Here's the Bitspower vertical GPU conversion bracket (disassembled). As with most Bitspower stuff it's very nice, CNCed aluminium, though anodised black which doesn't fit the walnut and shiny aluminium of the rest of the case.

    Thanks Andy (Vault-Tec) for the advice on stripping the anodising with sodium hydroxide - from a bit of reading chromic/phosphoric acid is cleaner at just removing the aluminium oxide/dye of the anodised layer and leaving the underlying aluminium and surface finish intact if anyone needs dimension-critical de-anodisation or wants to strip the reanodise. I'm going to sand down to mirror surface, and have caustic soda granules already and no want to get phosphoric or chromic acid and the hazard and difficulty that poses, so caustic soda it is!

    I used 12 teaspoons (~60mls) of caustic soda granules in 3l of water at around 45C. Very quick reaction! Stripped the anodising layer in around 90 seconds. Slower would probabIy be better (less chance of pitting from localised rapid reaction with a faster overall stripping apparently, though I saw no issues). I put screws in all the threads with medium strength loctite 243 threadlocker in to seal to preserve the anodising on the screwthreads to keep them anodised and hopefully prevent galling in future.

    Here's the vertical GPU bracket after and assembled - here with both 'struts' for 2 vertical cards - it'll be with just the left-hand gpu strut used. The odd smudge there is just a bit of dye and smut that's stubborn to get out of the material-blasted aluminium with an old toothbrush - will go with sanding and polishing.

    A little bit of lapping of the flat faces of the pci-bracket plate with 600 grit sandpaper. It's quite delicate with chamfered edges... I'll only be using the left-strut to vertically mount the GPU (the other one is unneeded restriction to passive upwards airflow). I'll end up mirror-polishing it all, bar maybe bits that only will be seen from the back of the case. I'm leaving the other bits unsanded for the moment, as I have some plans for that solid block of aluminium at the end and need to keep the faces dimensionally accurate/true until that's done...

    You will hate the decision to polish such a complicated part. :lol:

    Yup. Especially because it looks like it has been bead blasted for a lovely satin finish.

    Personally (but feel free to ignore me) I would polish the face edges and leave the rest satin. IMO it will still look incredible, but you won't sacrifice your sanity. That is why when I talked about doing the BMX parts I said I just go over it will the finest steel wool and leave it there. If you attempt to go further? you will see what Cheaps is getting at lmao.

    You were fairly right Cheaps, though not as soul-destroying as you'd have thought - fairly sure Bitspower went for an easily anodised and easily workable aluminium alloy (probably 6061) so a4 sheet of wet'n'dry sandpaper on a flat surface/plane, with most of the surfaces being flat meant most was surprisingly easy, and only a few intricate surfaces needed sanding with sandpaper wrapped around a small flat aluminium piece to get to the fiddly bits.

    I was merely unable to calculate the size of your 'ball locks'. :thumb:
