Description

Brain dump:

I built this machine mainly for gaming (VR as well) with portability in mind. I'd never built a computer before and have a lot of thanks to the SFF community for all the recommendations. Also, massive props to the creator of the S4 Mini, Josh Sniffen. The guy is an amazing engineer/designer/creative/person and has incredible videos on a lot of things SFF.

After completing, I'm extremely happy with the build! Stock, the 1080 mini had a slight coil whine (which may be more noticeable with the S4 Mini) but I was able to to undervolt the GPU following this youtube video and the whine is now practically inaudible!

I wasn't expecting the 330w power brick to be so massive.. definitely makes me consider doing a brickless build but I prefer the extra power of the 1080 vs. a 1050ti.


Edit: also, thanks r/sffpc for the tips!

Stock has a slight coil whine but appears to be remediable by undervolting.

Slick build. As an owner of S4M-C and S4M, Skyreach is the easiest case that I ever build in. I'm also a huge fan of Josh myself, he helps me mods the case and a very delicate dude. Sadly many have stolen his layout /ideas and attacked him with fraudulent lawsuits.

Ughh that's terrible to hear. I haven't had any direct communications with him but have seen him in practically every SFF thream possible... he's a legend

The smallest build I've done was a Shuttle, and that was challenging enough to find parts that would fit. This build is incredible - very well done. Did you know that all the parts would fit, or was there some trial and error? Re the coil whine, mine was caused by the PSU. Changing the aging Antec to an EVGA 80+ Gold cured it. I'd not come across the undervoltage method before, so thanks for referring to it in your description - I'll take a look.

(edit: ugh my comment was truncated -_- wth pcpartpicker...)

Thanks for the compliment :)

I "knew" that the parts would fit based on my research but tbh was a bit concerned after I saw how big the 1080 was. There was a slight bit of manipulation getting the GPU connected to the MoBo but overall it was pretty easy.

Yeah, I'd heard the PSU could be the cause of coil whine but it seemed to only occur when I started to game (under load) and thus I concluded that it was the GPU. It could have been a combo of the PSU + GPU (under load) but ¯(ツ)/¯. Plus the HDPlex400 + 330W power brick were sort of deal breakers for this build so not much I could have really done there if that was the cause. Glad to help out with the undervolt method as well. I was surprised how easy and effective that was :D

You thinking of snagging that 400w AC-DC from HDPLEX? It’ll be some customization to the GPU pin connector / wiring pin for the snug fit to sit next to GPU; if anything.

It would literally eliminate the battery. I was all game for it but then I hated the idea. Luckily it’s comjng out soon and shipping shortly after purchase from Larry at HDPLEX. Accommodating towards a brickless build. Plus assist in any electrical hiccups as it’s really a 450w from HDPLEX.

char_eric submitter 1 Build 2 points 1 month ago

Oops, missed this comment. Wait so you're saying with the 400w AC-DC HDPLEX, it'd be brickless?! This is very interesting...

MexiChris 1 point 1 month ago

Yes sir, only thing, theres been mixed reception on it fitting with the Zotac mini models. When Josh streamed about the AC-DC form HDPLEX two weeks ago on youtube, he touched on it lightly and stated it wouldn't really fit; but didn't clarify how so or why. I even asked multiple times myself on the live chat. He did do a lot of altering to the Nano Vega he was working on and had me thinking if there were some mods done, like the rewiring he did, GPU shroud-less, etc. it might be possible. I haven't dug into Small Form Factors to see what people might think or have on info. Might have to try the Sketchup model to test it.

I really need to do a build like this but with only AMD parts.

char_eric submitter 1 Build 2 points 2 months ago

You should! I was seriously considering AMD but went intel since I have a gsync monitor ¯_(ツ)_/¯

You can check out my reddit post for AMD recs (forgot to add that to this build as a resource).

MexiChris 2 points 1 month ago

Mine will be a mild AMD Ryzen 5 2400g build in the NFC S4M case. Sadly no funds for graphics card though as I figured, if I spent a decent amount on my build, my son should get his own entry PC that he can build upwards with me.

So the Zotac 1080ti Mini GPU + better Ryzen CPU is on hold for my build. I did snag some high end goodies for my build though: G.Skills RGB 3200 - 32gb, Asus Rog Strix x470-I, Noctua NH-L9a, HDPLEX 400 AC-DC and the list goes on. I suggest you jump on the build too! Char_eric build came in super recent with a simple clean setup. That’s kept me motivated towards my build.

MiggityMiner 1 point 2 months ago

wow, that's a tight fit. Nice work! Would be interested to see your temps at load

char_eric submitter 1 Build 2 points 2 months ago

Sure, and thanks! I'll get some more build pics up and benchmarking details.

MexiChris 1 point 1 month ago

Sits here waiting 12 days patiently for more updates on this photos and temp logs... the build is amazing. Still surprised I found someone on here that’s built one too.

char_eric submitter 1 Build 2 points 1 month ago

Called out! Sorry, I actually just BSOD'd it before the holidays and haven't had time to fix it :(

I haven't forgotten! I'll get those up asap!

MexiChris 1 point 1 month ago

That's totally understandable. Wondering how that came about. Looking forward to updates for sure now.

char_eric submitter 1 Build 1 point 1 month ago

I was setting up VR at my parents for some thanksgiving VR fun and was tinkering with the audio drivers because sound wasn't outputting and think I borked it.. good news is that it's probably just software, bad news the bootable usb isn't booting to repair :|

char_eric submitter 1 Build 1 point 1 month ago

Still haven't forgotten about you! I'm still troubleshooting the BSOD. Currently I'm leaning towards the power brick and thus have ordered a replacement coming tomorrow (fingers crossed). Will keep you posted.

Great build dude, motherboard LED's look great peeking through and always good to see more SFF builds around!

char_eric submitter 1 Build 2 points 2 months ago

Thanks! And yeah, I really like the stock MoBo LEDs. Thinking I may look into syncing up the power LED if possible too

Judespace 1 Build 1 point 2 months ago

How did you fit the 1080? I thought the s4 mini was too small for that ZOTAC 1080.

char_eric submitter 1 Build 2 points 2 months ago

You should be pleased to hear that you are mistaken! You're probably thinking of the s4 mini classic (S4MC) which required some extra modding to fit the 1080. The S4 Mini (S4M) that I have comfortably fits the 1080. You can see Josh talking about the difference here.

Judespace 1 Build 3 points 2 months ago

No idea they made a new case, I’ll have to check it out now.

How hard was it?

char_eric submitter 1 Build 2 points 2 months ago

Not hard at all really. The biggest trouble I had was testing all the hardware worked. I couldn't get it to boot but then realized that the RAM wasn't properly connected (sigh).

Getting the GPU connected to the MoBo was a bit tricky but ultimately not too bad. I think I stripped a screw, removing the case so I'd forewarn to be careful doing that. Otherwise, pretty straightforward :)

Thanks!
