Hi Folks,

After some thinking and with a bit of advice from @Emlyn_Dewar, I think I'm starting to get my head round the mini-ITX air-cooled mini PC Idea.
I haven't touched PC hardware for decades, so would appreciate some of your advice.
For starters, I'd like to put together a shoestring budget box, just as proof of concept & try to make full use of discounts on Aliexpress or buy used parts on ebay.

The build spec that I came up with is as follows:

- Use: home desktop use running a light version of linux. Vector graphics editing, a bit of audio editing, occasional Arduino coding and some very basic FreeCAD. Box being built with a view of <12yo kids gaming in the next few years (steam I guess, given it's a linux), and some console emulation. Maybe some chess database work.
- CPU: Ryzen 5600G
- Case: RGEEK L65S (197mm*197mm*65mm)
Alternatively, there's a taller model RGEEK TA80 (197mm*197mm*80mm) - not sure if the extra height is worth it and makes a big difference (to cooling or component placement)?
- Motherboard: B550 mini ITX. Probably whatever's going cheap on aliexpress on 11.11.
- 2 nvme drives - it is my understanding that a second drive can be mounted with a pcie to nvme m2 adapter. And I'm not using the gpu slot anyway.
- Fan: Thermalright AXP-90 X36 seems to be the best cheapo solution, but I'm considering Metalfish Z-39 too.
- 16GB DDR4 RAM.

I am really stuck with the PSU choice. I guess I'm feeding either a 90W or a 120W 12v external brick into the box and putting it through either a tiny pico jobbie
e.g. Small
Or a larger board
e.g. Larger

What would be your recommendation for the wattage and what's the benefit (if any) of the larger board?
Also with nvme drives, do they need extra cooling? e.g. fan+heatsink

Any other components that I missed out? Recommendations to avoid anythign like plague?

Thank you.
 
There must be something wrong with my brains, as I'm hopeless when it comes to processing information from a video. I can read manuals, guides & articles all day long, but youtube just doesn't do it for me at all.
My current problem is that I really don't need any significant GPU power right now. I expect that I'll need some in 2-3 years. A 5600G build will be very fast for my current needs and might stay relevant a few years down the line.

Alternative thinking was to use the likes of a Metalfish S3, put a mini-ITX board into it with a powerful non-gpu CPU and some really cheap (£40) GPU from years ago and upgrade it a few years down the line as and when I need it. I haven't tried speccing it yet.

Also, I'm a gambler. I like Chinese stuff. And on 11.11 you tend to get it half price. Sometimes you win, sometimes you lose, but I just love the adrenaline rush I get when I open a parcel with some goodies from a manufacturer with an unpronounceable name. But there's a difference between being an idiot gambler and just being an idiot - I'm not going to buy rebranded Chinese recycled ex-mining GPUs for example!
 
Never been to China (it's on my bucket list though). Have a few friends from there who introduced me to the 11.11 concept.

SKTC A09 - sounds great! Picos make me somewhat nervous. A pico looks like the weakest link in the whole build, and if it goes, it will likely take the rest of the build with it. A09 is not much bigger than pico-based cases but it's smaller than GPU-equipped boxes like the S3. And I can put a bit more cash towards a decent PSU.
What max wattage do I need? Will a 450W "be quiet" from OC suffice?
 
Right, Flex-ATX. Certainly not the same thing a SFX. I was confused for a moment.
Looks like there are quite a few used 250-270W boxes goind for peanuts on ebay. Not enough wattage?
Some 350W but not many higher than that.

Are server PSUs any different from regular PSUs? Say, ones from a Dell PowerEdge R210 rack?

Looks like server PSUs are fine for the job.
I just can't see how a 5600G system can go over 350W... If I had a separate GPU drawing 200W, then the total for the build could approach 350, but for an APU 350 seems to have plenty of headroom.

Motherboard wise, at the moment, there's only JGINYUE B550i Gaming, JGINYUE B450 and Used :confused:ASRock X370 that support 5600G in mini-ITX format on Aliexpress. Reading online reviews, they seem to be decent value for money, but:
Right now I'm looking at £67 delivered + wifi card, let's call it £70. A Gigabyte A520I is selling in the UK for £97 and is presumably better quality with better support and warranty. Right now the price difference does not go in favour a gamble on Ali.

Is there much point in buying 32GB of RAM instead of 16GB?

£50 will certainly help keep me in the budget, but are you talking micro-ATX as opposed to ITX size? ITX seems to be harder to come by and twice the price.

A09 case APU build example:

Log - Finally found a case/SKTC A09 3.8L for my Mini-ITX APU-Builds/no graphics card!

My previous two Mini-ITX builds APU-Builds (listed below) had wasted case space. Just to be clear; APU-Builds have no graphics card. I am not interested in the latest/greatest Frames per second GPU's therefore, the built-in Graphics on the CPU chip works just fine for my web browsing, pictures...
smallformfactor.net smallformfactor.net

I found it while I was researching Delta flex-ATX PSUs, but the whole build is very close to what I have in mind.
 
I was hoping to keep the whole build under £200 :p. But it's easy to double that budget if I'm going for all the "could haves". At the end of the day it's all slightly old tech and it does not make too much sense to put a lot of cash towards it. I read that 5600G can be picky with what RAMs it will work, so I'll probably fork out the cash for corsair vengeance LPX. They seem to come in different frequencies as well as different sizes :eek:

Pulled the trigger on the CPU fan. AXP90 X36. £14.50 delivered from Amazon. Delivered next day. Looking good. Don't think I could get it any cheaper.

Also pulled the trigger on the 350W Delta PSU. Seems to be well-reviewed in the write-up that I linked to. It won't accept a 20mm fan, so not a good candidate for Noctua mod, but apparently the thing runs dead silent unless you're really pushing it, in which case it fires up at full speed (but keeps things cool with a lot of airflow). Sounds fine to me.
There were a couple kicking on ebay for £20, but they were caked with dust. I went for £35 delivered, with the seller claiming that it was removed from a brand new server.

Used 5600G seem to be going for about £80 on ebay UK. Cheapest one on Ali was £43 taxed & delivered, supposedly brand new, shipped from Turkey from a seller with 0 feedback. I might be a daft gambler, but I'm not this daft. Next best option was £64 discounted to £54 with Alicoins (loyalty customer discounts for the uninitiated) from a seller with 100% feedback rating and 90-day free returns policy. I pulled the trigger and I'm in for a couple weeks of chewing my seat with my cheeks, waiting for it to arrive to see if it's a dud.

Ali B350i-plus motherboards are about to go on sale for £55 new. I doubt that they will go much lower on 11.11... Tempting to pull the trigger soon. Also a 90-day free returns option.

Real problems will be if my cheap hobo-PC build does not post. Will be hard to figure out which one of the low quality parts is not cooperating:(
 
Only about a fiver difference between B550i gaming and B350i.
It now looks like I might get 550 for about £50 or 350 for £45 in the end, once all discounts are added up. That's cheap enough for me to take a gamble.

How are you finding jginguye bios updates? Or is it the classic case of "don't fix it if it ain't broke", if it works, it works?

In regard to RAM - thank you very much, wasn't aware of that! You've got to remember that last time I did anything to PC hardware was when ascii dungeon crawlers were still in vogue.
Any point going for 3600hz for a couple extra £ ? Or will it be too hot for the small box if I start pushing it?

Also, has there been any development in wifi cards in the last 20 years or so?:cry:
If I have a spare PCIE card from about 2004 and the motherboard has a pcie wifi slot, can I just plug & play, or has there been a 101 standards introduced in the meantime?

Am I likely to need extra cables, etc? Or do parts tend to come with all the necessary connections?

Found a bigger brother of the A09: A10.

A10 7.3L M-ATX Chassis
Slightly bigger version for mini-ATX that seems to have the space for a small gpu and should be able to house a more powerful 1U psu.

Thank you. They certainly do, but I suspect that the cooling there is closer to miniPCs like mini Optiplexes and Elitedesks.
Also, if going for Flex-PSU, there's space in the case for a proper fan. And I'm uneasy about going for smaller boxes with pico PSU+brick.
So to me, the mini ITX form factor makes a lot more sense in A09 case than in the likes of L65S. But that's just me.
 
The Delta has arrived, and I quite like it. It's got a built-in fan controller and seems to be dead silent on low loads and moderately loud on full speed. I guess it will depend on just how hot the 350W psu will be running under everyday load.
Got myself a B550i gaming Jgingue for £49 in the end, A09 case with USB3.0 for £28 + £2 wifi card, and a pair of 16gb DDR4 corsair rams for £44, which puts me at about £225 for the whole thing. Still need to get a couple used nvme SDDs.
Over the original budget, but I hope that a decent PSU and decent ram sticks are a worthy investment.
Waiting for 11.11 could have saved a few extra pennies, but yesterday was almost as good discount wise.

Micro ATX would have been cheaper, but smallest Flex-powered case is twice the size of the A09, and smallest SFX case is 3 times the A09. I suspect that the most sensible budget build is to stick a micro-ATX card + GPU into a ~13L SFX case.
 
Thanks.

Looking ahead, is there a good idiot's guide on the best way to connect the PSU to the motherboard? And decide what gets the power directly from the PSU and what gets power from the mb?
 
Not without hiccups, but I've plugged all the bits together tonight, and the pc started.:cry:
Plugged in an NVME with Win10 from my laptop and a portable 6" HDMI touchscreen (because I did not have an HDMI cable for the big monitor), just to see if the motherboard will post. Not sure why the pc cycled through the bios startup 3 times, but then it happily booted into win10.
So it not only posts, it's capable of booting up a system.

£56 Ryzen 5600G CPU was a problem:confused:: did not arrive, and the seller has provided a wrong tracking number. Tried contacting the seller - no response. I requested a refund and got the money back almost instantly, so really don't know what his endgame was.
Ended up spending a bit more on a used 5600g off ebay

Wifi card was also an issue. The seller had the mobo listed as "wifi PCIE compatible". I bought a mini-PCIE card just to find out that the slot is, in fact, an M2.
Now have an M2 on the way, but for now I am wifiless.

Anyway, all works, so now I just need to buy the new nmve, get all the bits into the box, and install the CPU fan on to the MB.
