The following is a verbatim writeup from a customer regarding this 4060LP STX build. I thought it would be good to get a customer perspective added for this build:
Mini STX X600 | Ryzen 9700X | RTX 4060 low profile build
Computer components
AsRock Deskmini X600 motherboard
Ryzen 7 9700X
Gigabyte RTX 4060 LP
HDPlex 250w GAN
Thermalright AXP-90 X47 cooler
Crucial SODIMM RAM
Samsung 990 Plus SSD
NFC components
S4T
X300/X600 4060LP Inset bezel (revision D)
GX16 cable
Power switch
Case stand
Misc components
ADT K43SW m.2 Gen 4 riser (20cm)
Resistor - SMD 100k (0402)
5mm motherboard standoffs
16mm washer that needs to be cut or 3D printed
This build has been over 2 years in the making. Ever since Josh uploaded his STX/A2000 build on YouTube. I ordered all the custom parts needed but never bit the bullet on the expensive A2000 video card. Finally, years later I got the X300/X600 4060 LP rear bezel and the Gigabyte 4060 LP and also the X600 motherboard instead of the X300
Tips for anyone that wants to do this build that I personally didn’t know going into it. Josh did mention some of these quirks on his discord post when he built his, but I didn’t read that post until midway through my build.
1. The X600 motherboard needs the resistor mod to accept the HDPlex GAN 12v power. Thanks to the discord members pointing me in the right direction to solder on the SMD 100k resistor on top of the existing. (I am not skilled enough to do this so I requested assistance from a friend)
2. The X300/X600 4060 LP bezel I got from NFC is revision D. It requires the motherboard to be lowered by 3mm for additional room to easier accommodate the 4060 LP. So replacement 5mm motherboard standoffs are required to replace the original 8mm standoffs. Because the standoff is now shorter you will need some washers to put on top of the motherboard screw holes as there is not enough space for both the front and back screws to go all the way in.
3. The adjusted position of the GX16 cable and on/off switch causes the internal frame to sit in-between the rear locking screw of both items. It’s pretty secure without a washer but if you cut a washer to put in between it feels more secure.
4. Because the rear locking screw for GX16 cable and on/off is now raised it interferes with the video card. I had to trim a little bit of the 4060 plastic fan shroud to get the video card to seat properly against the rear bezel.
5. The front panel headers on the mini STX board are smaller than on normal ITX/ATX motherboards so you will need to do some minor rewiring.
6. There is not enough clearance to plug in the CPU fan cable to the header. You need to get creative on connecting the CPU fan.
7. The Gen 3 ADT link R34SR I had originally purchased did not work, either because of PCIe generation issues with the X600 board or I bent the riser cable too much. Windows would recognize the card but whenever I switched to the GPU from the onboard graphics it would freeze up Windows and detect an issue with the card. I had to purchase the K43SW Gen 4 riser. The Geb 4 cables are a lot stiffer so requires some effort bending.
8. You will need some perfect length case screws as components will be right behind a couple of screw holes.
The above are the items slightly different from Josh's X300/A2000 build due to the X600 and 4060LP. After watching that YouTube video and the above comments you should be set for building a similar setup.
I also had some issues with the system powering off suddenly, I really don’t know why and it seems to have fixed itself.
Thanks to the discord members for pointing me to the forum/post for the resistor mod and Josh for providing the above solutions.
