    When the case came I was a bit shocked about its size

    20190730_184928.jpg

    Here it is next to an O11

    At that time I experimented a little bit with Pelletier cooling and considered adding it to the loop

    20190811_135038.jpg

    I managed to get the loop temp below ambient in idle, but once the 9900K went to full power, the Pelletier draw more power and became inefficient

    20190811_122933.jpg

    So finally I discarded the idea. But it was a nice try anyway :brrr:

    So I decided to beef up the cooling capacity of the InWin 928 a little bit, because despite its size it can host "only" two 420mm rads.
    I added a 240mm rad on the back of the mobo tray.

    20190924_174023.jpg

    It is a rough 25% increase in cooling area and probably not worth the hassle, but the heck with it...


    20190924_174951.jpg


    20190924_191608.jpg

    I added a 1mm thick sheet of acetal on each side of the mobo tray, in order to hide the huge original cut-outs

    20190924_192446.jpg

    I also had to sandwich some pre-shaped aluminum with the thickness of the tray inbetween those sheets, because otherwise some fittings were just in the air.
    The original cut-outs are quite big...

    A first test fit...so far so good

    20190925_212008.jpg

    I wanted the loop as clean as possible, so much of the loop is hidden in the case

    20191004_150312.jpg


    The original fans have been replaced, as they suck. Imho, all case manufacturers should stop to equip their cases with pre-installed fans and sell the cases at a lower price.
    Who the heck does not replace their ****? I do not know how many noisy, crap looking fans I have flying around my shop. What a bloody waste :wallbash:

    20191004_164800.jpg


    I wanted to integrate the RTX5000 in the loop and that required a good amount of research, which cooler might fit.
    Well, at the end of the day it is a reference design, so basically any RE cooler would do...with some tweaking.

    I went with an EKWB cooler, but it needed a completly new cover, since the power connectors are oriented differently on the gaming cards.
    This was a bit tricky, because all the cooling channels are in the cover, not in the metal cooling plate. So a half day of measuring, re-mesuring and drawing was required.
    But at least the cooling plate fitted the PCB and that was all that mattered.

    I also made a new inlet with 4 ports and new RGB logo and a nice looking back plate.

    For whatever reason I can't remember, I have not made a single picture of this...

    I moved the location of the two PSU cages a little bit, so they are closer together, which gives a bit more room for the cable management.

    20191004_164823.jpg

    The dual pump is not necessary, but a single one look a bit out of place in the huge cage

    20191009_082015.jpg

    Finally I added some acetal covers on the bottom. The HDD trays are still removable which makes revisions to the cable management more easy.

    1,5 years down the road, however, my enthusiasm for the case is gone, and am I left with what bothered me from the very beginning - the noise...
    The InWin 928 is a masterpiece of a case and I still like the design, but it has a major flaw - at least for me. It is basically an open design, since there are considerable gaps between the aluminium frame and the side panels - otherwise no airflow.
    With 14 fans inside, spinning at a meager 500 rpm, there is a distinctive hum.
    Under load...well figure yourselves :eeek::eeek::eeek:

    No problem when you are gaming, but when you do CAD work half a meter away from the beast - tiring to the least.

    Most likely I can improve this with Noctua or be quiet! fans, as the Alpenföhns are not really the quietest ones - although significantly better than the OEM InWin fans.
    But the look so pretty :grin:

    Covid lockdown gives me plenty of idle time, so I decided it was time to change.

    I did some research which case would do better and I finally ended up with the be quiet! Silent Base 802.
    The design is a bit dull, but I like the modularity, the complete dismountability, size and relatively good bang for the buck.

    First action, complete disassembly, measuring and re-modeling in CAD.
    I used a white one for this, way easier to take measures.
    I kinda liked the black and white theme, but it would have looked a little bit out of place, so finally I went with a black one...

    20210106_150923.jpg

    Got some help too....

    The prime condition was that I want to carry over the hardware 1 to 1.
    Even though it is soon two gens old, it still is a hell of a good CAD rig.
    My software is single threaded, so core clock is all that matters and the 9900KS gives a reliable and stable 5.3 MHz. I won the silicone lottery - for a change - yeah!!!:clap::clap::clap:
    So no reason to change, new CPU, new mobo, etc...

    Also I want to salvage almost all of the cooling hardware, pump, fittings, fans.
    Only the res and the rads need to be changed, the current ones simply don't fit in the smaller case.

    Lastly, I want to carry over the overall look with the vertical tubes, mainly because I do not want to touch the GPU cooler...

    First part to be made was a bracket for the aquacomputer quadro and farbwerk. I f..king hate Asus Aura and Fan Control, so I want all fans and external RGB to be managed without it.

    20210122_100508.jpg

    A 6mm aluminium plate with two 5.5mm deep recesses

    20210123_102356.jpg

    This fits perfectly to the SSD bracket of the case

    20210123_123216.jpg

    Hold in place with 3M sticky tape, done. The recesses are necessary because the cut-outs in the brackets are deep drawn and have a collar - and because there is not sooo much space between the mobo tray and the side panel.
    This has a 10mm thick anti noise foam on the inside. So to fit all the connectors, every milli helps...

    Next came the pump bracket.
    This has to be a two piece design - otherwise you can not put it in place.

    20210123_133440.jpg

    The pump has anti-vibration mountings, which need to be secured with M4 nuts. The bottom ones can not be accessed anymore, once the bracket is mountet, so the pump need to be installed to the bracket first.

    20210124_171901.jpg

    The middle floor has a 8mm deep draw, so you cannot swivel the pre-mounted pump and bracket in place, hence the two piece design...

    The covers on the floor above the PSU are a snap fit and a bit flimsy for my taste. So I decided to make a new cover out of 8mm acetal.

    20210123_165529.jpg

    I wanted to have an RGB gadget in there with an iluminated plate and a logo cut-out in the acetal. So i milled it down to a remaining thickness of 1.5mm, in which the logo should have gone.
    But see for yourselves...:wallbash:

    20210123_192006.jpg

    The acetal got warm, the thin layer bended a bit...and got sucked up by the endmill...:waah:
    Should have known better and fixed this area with double sided tabe beforehand :rollingeyes:

    Gone too far by now to do it again, so I decided on a different solution.

    20210124_162815.jpg

    Wasn't the last hickup though. The bottom hole was not supposed to be there :eeek:
    At least the location pegs turned out fine...

    The test fit is ok.

    20210124_171457.jpg

    Drilled out the hole and turned a mating plug

    20210125_091547.jpg


    Sanded acetal is a fingerprint magnet. It also does not really match the black colour of the case.
    So I just put some vinyl on it.

    20210125_125423.jpg

    20210125_125029.jpg

    That's quite allright

    This also has the benefit that you can plot all sorts of things in the vinyl.

    20210125_195655.jpg

    Not what I originally intended, but it has to do for now...

    This isn't really a case mod. Sorry. Only a few parts to make. Apart from a few holes in the PSU floor for the fittings, the case remains untouched.
    Need to make a matching reservoir and that's it.

    20210129_150618.jpg

    I need a custom one, because the available ones are either 240mm or 360 mm and I want mobo height, 305mm.
    Also, the mobo is E-ATX and it covers the pass through cut-outs for the cables.
    Behind the res are 5 openings where you can place HDD drive bays.
    Cables can go through there, but I need an opening in the res for this...

    20210130_122737.jpg

    Need some grooves at the back as well, because those HDD openings have collars too.

    That is the current state...

    Bottom half is finished.

    20210130_215506.jpg

    It gets RGB from both sides, the strip on the right and the mobo on the left.

    The res is finished.
    It is a three piece design.

    I made a frame from 3mm acetal to hide the o-ring.

    20210131_111046.jpg

    Then I milled a matching recess in the acrylic....

    20210131_111115.jpg

    ...and taped them together before drilling and cutting to size.

    20210131_111728.jpg

    This worked quite well.

    20210131_150157.jpg

    The sides are all painted black, so the RGB will hopefully just illuminate the water.

    20210131_151511.jpg

    The frame is a bit elevated above the acrylic to give it a more 3D like look
