Hello All, As I near completion with a build I've been working on I figured I'd show my progress and maybe get some input.

I started this build with the plan to 3d print a new case inspired by msystems' DeskNano. I initially was just going to go the X600 5700g route but I wanted to be able to play some games at 4k as this will be a portable Lan gaming machine and mainly a HTPC.

It started life as a 13100 with a tesla P4. While it performed well it wasn't quite enough for my goals. I ended upgrading my main rig to a 14600k and swapped the 12600k into the mini then ordered a Yeston 3050LP. After discovering my m.2 to x16 adapter was only pcie 3.0 I ended up finding a m.2 to x4 card then just got a riser cable.



After playing around with undervolting/OC'ing on the 3050 I was quite impressed with the machine and decided to figure out a layout to keep it as small as possible. After a few iterations I ended up with this.




It comes in just over 2L and that's brickless! Big thanks to sandyware for the inspiration on that and his resistor mod (waiting on those to come in still as I have yet to test it with the internal psu) I went with the same Mean Well LOP-300-12

I'm not entirely sold on the snap in grill. I may alter the design to put a screw on grill to add some rigidity to the whole system.

This SFF stuff is addicting but sure is fun. I have another mid section printing right now that fixes a few issues then I need to order a 40mm notcua fan to help cool the new PSU (what the front grill cutout is for)

I did like that I could power/output the 15.6" portable display via the type C connector with the tesla p4 but I'll deal with another cable for the bump in performance.

Anywho, What's your thoughts on making the grill a screw in component to make it more rigid? or is the difference going to be negligible with the pattern of the grill?

Thanks and I look forward to the criticism😁

How did you make your deskmini get a 12v intake indtead of 19v?

Wouldn't be surprised if nothing. Asrock's N100DC-ITX mobo (and at least one other that I don't remember the name of) is spec'd for "19v ±10%" but has no issues with 12v.

I'm going to use sandyware's method. I have not done it yet however.

My parts showed up today so I'm hoping I'll get it installed this weekend to try it out!

Can you tell me if its safe or not because this is something I have also looked into and was hoping if you could test your pc after your done installing it and share the results with me.

Ok a little update. So I did the mod and hooked up the meanwell PSU directly to the MB.

It does work and there aren't any errors/issues with the system however performance dropped off pretty considerably!

So after playing with it for an hour or so I found that the core voltage for the CPU is barely 1v and max TDP on the cpu even with cinebench R23 or CPUZ stress test is only 40w. I played with everything I could think of in Bios before admitting defeat. So I de-pinned the power at the PSU and plugged the stock brick in to see if I could make sense of it.

Now this is where it gets interesting. even with the 19v psu max TDP is still limited to about 74 watt's (never checked it before) Bios P1/P2 is set to 120w. I then installed XTU to see if I could squeak more performance out of it and OC'ing is locked out on this hardware, but it did confirm that there are no thermal or power issues present.

I'm going to take a break on it but to summarize. Yes the mod works and yes it runs fine on 12v. However it took a hit in performance.

I'm going to try finding a plug to wire directly to the PSU to plug into the factory socket to see if that changes anything on the 12v mode (used 16g wire so I figured I'd be good)

Oh and holly hell is that resistor super tiny! lol
