    I have a new question for you:

    Whould it be a problem if the motherboard standoff will be a part of the side panel? This means you can't remove the panel without removing the motherboard. The advantage would be, that I don't need the middleplate. Then I will redesign the inner body that will have a bottom where you can screw the radiator. This will make mounting radiators much easier.

    Disadvantages:
    - you have to unscrew the motherboard to get access to its backside

    Advantages:
    - increasing stiffness of the case
    - easier installation process for radiators

    angled type 2 is awesome.

    I would favour hifi feet located in the corners. With one or even two pumps running in the case there's potential for vibrations through the feet and into the desk creating more noise than you would like. If you have some sort of standard screw-in round feet then we can buy (or you can supply at additional cost) separate acoustic isolation versions.

    If you buy big enough feet you could have them sticking out giving the case a squat purposeful look.

    I do like the InWin version best - how about also looking at rails along each side sticking out like ski's? Like the case on this one except not fugly. https://www.scan.co.uk/products/coo...MIwLecx46F3AIVZrvtCh2UQQpkEAQYASABEgL23PD_BwE

    Sounds clumpsy. That’s my initial reaction. To counter this: What about adding an opening to access motherboard backside (cooler / waterblock mounting / m.2 access)? This opening will can be closed off via a cover plate that is flush mounted to the back panel. To accommodate the flush mount, the motherboard standoffs would have to be slightly taller. What do you think?

    In the A4 you need to take the motherboard out to access the back. I don't think it's a big deal.

    What you mean? Why do you want to access that? I think it would be hassle.
    Look at the Ncase M1 easy access of the back with the removal of the sidepanel

    My 2c; I don't know how common it is for M2 slots to be on the back of motherboards but it would have dual effect of making it difficult to swap out and also reducing airflow for cooling.

    Having said that, I've not had cause to look at mine for three years.

    Almost all of the ITX boards I've looked at have M.2 slots on the back. Having to completely remove the motherboard in order to gain access to the M.2 slot and the backside of the CPU mounting socket would be a PITA that I'd like to avoid, if possible.

    We'd also be losing cable management space...

    Talyrius: You will not lose cable management space because you can route the cable first and than install the motherboard over it.

    Not sure about other people but I rarely remove my MB... so yes this solution is less user-friendly but I would rather have better thermal or better anything and have to deal with the trouble of losing 1 hr every year if I need to upgrade my ssd if I can enjoy a better solution during this year long.

    If we can t having it all, then this is at least for me ok.

    Some of the AIO's have big ol' back plates which need to be accommodated - I assume standard mobo standoff's are good enough?. Plus side - if the M2 cards are right up against the side panel maybe you have found yourself a big heatsink.

    I really like the angled 2 version


    as long as I can still use the same cables I already shortened for the A4, whatever you change inside is fine with me - but I don't want to have to buy new longer cables just to shorten them again

    "The only limit is your own imagination"

    I'm not sure this is the best marketing slogan for an SFF case :D

    Or a short.
    Also you don't need to cool NAND flash. All you want to cool is the controller chip. NAND flash has higher endurance when it's running at higher temps. Cause the energy and thus voltage needed to tunnel charges onto the isolated control gate is lower at higher temperatures, which in turn means less damage to the oxide layer in between per program-erase-cycle.
    Look at this. Only the controller really gets hot. What those copper stickers on Samsung SSDs do is spread that heat over the NAND chips, cooling the controller while heating the NAND.

    I prefer the angled feet, or the jonsbo style feet with just the single vand going across the bottom, other than that, good luck!

    Oh I made a small mistake. The height of the feet obviously change that angle too. The higher the feet, the smaller the angle becomes.
    So three conflicting design goals:

    stability: as low as possible with as wide a base as possible
    design: low with a narrow base for the current design
    cooling: as high as possible

    Congratz on your very own ITX human, Dan. I hope the sleep isn't too bad :sleep:
