XPS 8700, install the XPS 8930 H0POM?
Motherboard upgrade, XPS 8700 KWVT8 to XPS 8930 H0P0M?
I've been slowly preparing an upgrade of my 8700. I have the 0H0P0M motherboard, 64G memory, nh-u9s (better than stock cooler), i7-8700 (not the K), a cutout for the back panel.. Anyway, the only issues are as described in detail elsewhere. i.e. on the 0H0POM there is 1. F_USB2, 2. F_USB1, 3. Card reader, 4. FP_Audio, and 5. F_PANEL. On the 0KWVT8 (the 8700 MB) there is 1. F_USB2, 2. Top Panel USB 2.0 connector, 3. Media Card Reader, 4. F_AUDIO1, 5. Power Button Assembly Connector.
Question: Are these items one to one or do I have to solder and disable them? Since I'm going from Dell to Dell (instead of some other type of move) I thought it might not be necessary to disable all of these things. However, I don't want to cook the H0POM. That would be a show-stopper.

Re: Can I connect the Power Button Assembly Connector (8700) to the 0H0POM without killing it?
no worries here at all. both use pin 6/8 for power switches c/w standard. understand you feeling a bit nervous but there is no risk of connecting 8700 front panel per switch to 8930 board

System board from XPS 8930 can be transplanted into other cases, including non-Dell. Review this case swap post for more ideas and answers to your question to resolve front I/O connections. https://www.dell.com/community/en/conversations/xps-desktops/xps-8930-case-swap-cpu-liquid-cooler-temps-upgrade-summary/647f8064f4ccf8a8def0e3dc?keyword=xps%208930%20case%20swap
I know that users have their reason and preference. But, the XPS 8700 chassis is not a good performance case to be invested in. While you can add a 92 mm bottom front intake fan, there is only one small opening in the back for exhaust fan comparing to multi-fan ATX chassis in the market. Therefore, it could restrict or limit the cooling from your better than stock cooler. Also, the top I/O panel and its cable may block some power supply larger than 150 mm to be used in the 8700 case. There is a vent opening on the side panel, on top of PCIe slots. Consider to use blower style GPU to draw in fresh air from side panel and push the heat out to the back.

@Chino de Oro Yes, I have studied that link, Thanks. But, it's about a swap to a non-Dell case and hookup. I think I can get away with a few things (main concern is the power hookup) because I'll be using the one from the Dell 8700). I will make the change to a newer case if it becomes necessary.
Right now, it is as cool as can be in the 8700 case, as the stock hard drive(s) are long gone (replaced by a qvo 8T and 2T dogfish msata), the optional Geforce GTX 660 that came with it does have a fan. I am not going to touch the stock cooler (it will be swapped out when I put in the new MB). But, there are total 3 fans in there now. Current temps are CPU (35c), GPU (35c), Ambient (20c) and the drives are below 25c. The i7-8700 shouldn't be that bad. But again, I'll watch it. I can always hot swap the old board back if the temps rise too much. But, this assumes that I don't destroy the new mother board when I hook it up. Which is what my question is about. i.e. Can I connect the Power Button Assembly Connector (8700) to the 0H0POM without killing it? I don't think the other stuff is as problematic with regard to damage. I'm not looking for a guarantee of success, just a rough estimate.

I have two 8700 one complete pc the other case has a HP mobo swapped in b/c stock board died. I was thinking of swapping in a 8900 board but has not got one yet. The 8700/8900 case are essentially identical. Dell standard mATX cases are what they are. I like their slanted looks and they are much better than good looking outside but terrible design inside 8910-30 cases in internal design. I consider 8700/8900 case classic oem mATX. Chino is correct that they are not high air flow cases. They are not XPS 630/730 full ATX case either but given their shortcomings they are still good ones if not super cool.

@redxps630 $80 - $110 or so on ebay or alibaba (alibaba's a risk though e.g. shipping). One last photo of the upgrade; very happy with it. The 4x pcie lane took an sas3008 and a little tape on pin 3 and 20Tb seagate spun up. Anyway, Thanks again:
