Case mods complete, and it looks great at this point. I don't presently have two 15mm drives to mount side by side on the modified motherboard tray, but the single drive I do have mounts to both positions and goes into the case cover just fine in either position. I will have the system torn apart again here in a couple days and I can post pictures of the modifications I had done to support the big drives. 10TB's of storage, here I come!
I'm really curious to see your mod. I am currently using my DeskMini 110 as a Plex server and I have 2 x 2TB Seagate HDDs in the bottom, I would love the possibility of adding the 15mm Seagate drives.

Going for the worlds smallest size, highest capacity, home NAS? Some super awesome 4K Shows?

Agreed. I'm looking forward to seeing the pictures. Right now I'm happy with the performance and features of my QNAP NAS but it's nice to know that you can fit such a high capacity in a small package. For reference, my 2 bay NAS is about 50% larger than the A300W, though the NAS supports 3.5 inch drives...

Look forward to the pictures. I'm mulling another build of one of these, but dumping the case completely. Not sure yet, as I may do an ITX 2600 instead. I have those (2) M.2-PCIe adaptors coming from the USA so if I can get that to work on the motherboard (as I have one I built for my mother) with a 1050Ti I will go with another one of these.

Now this makes the A300 interesting again, since the unsoldered current APUs had a considerable heat disadvantage compared to the Intel Cores, requiring higher Noctua rpm. And I only want to build near silent SFF PCs where the Noctua runs at max 1000 rpm most of the time (my i3-7100 needs 800 rpm most of the time and is practically inaudible behind the 27" screen in a silent room).


"...The other added bonus will be to the Ryzen 5 3400G, which will not only be released $10 lower than the 2400G, but it will now come with the 95W AMD Wraith Spire CPU cooler bundled in box, an upgrade over the 65W version previously used. This CPU will also be Indium-Tin soldered on for better thermal performance and potential in overclocking headroom. ..."

While it seems like the inclusion of the 95 watt cooler is a good thing, it's likely that the new cooler will not fit in the A300 case (even when modified) requiring one to purchase a Noctua HS. I'll be interested to see the performance of the 3400G once test data becomes available. Leaks from a few weeks ago show about a 10% gain between IPC and clock improvements.

I was refering to and had highlighted the text part about the new soldering. The current 2400G is not soldered and runs cosiderably hotter than the soldered Intels of the same TDP league.

Yes, that's true. For those who don't yet have a processor for their A300, the 3400G looks like a really nice APU.

Here we go, pictures of the A300W with the 25mm fan and mods required for 10TB of storage. The mods may look difficult, but they weren't, nor were they time consuming to make. Enjoy.

The only visible modification is on the very bottom of the back of the motherboard tray, where a 1/4" section is removed. One can see the top side of the hard drives and the Velcro straps peeking out from the hollowed out section. The section removed is part of the base support, so only the center section is removed, while the edges remain in place for support. It's an ugly hack, but it's hidden in the back. The rest of the mods are completely hidden inside.


This shot shows where the four flattened metal hoops were, they looked like cable management tie down loops. They were locating/lockdown receivers for the motherboard tray/case interface, but they were in the way.


Here are the sections of the underside of the motherboard tray that needed to be modified. The drive standoffs were ground completely away, becoming horseshoe shaped openings.


The left side bulkhead was removed entirely. The right side bulkhead only had enough material removed to allow the 15mm drives enough room to be mounted, hence the hollowed out ugly hack in the first picture of the set. The center bulkhead retains only the vertical component that is perpendicular to the motherboard tray, all components parallel to the motherboard tray are ground away leaving just a skinny wall between the drives.


Here is the modified drive mounting



Compared to stock drive mounting


And here is the complete assembly ready to insert into the case.


*****A few notes to keep in mind. This is a very tight fit, but it does fit. Sliding the motherboard tray into the case goes pretty easily, but removing it was not easy. I actually had to flip the Velcro straps over at one point because the fuzzy side was binding and catching on the case. So, since the motherboard tray is sliding into the case on the Velcro straps, I recommend greasing those rails *BEFORE* you insert it because it is difficult to remove later.*****

Wow, you really had to shoe horn those in there. It's nice to see that they both fit. That's a lot of capacity in a small case.

Hello

I would buy an A300 plus Ryzen 5 2400G (with Noctua NH-L9a-AM4 ) and Western Digital WD SN500 . I do not want spend a lot in RAM and I am not a bios expert. Anyone can recommend me a cheap 2x8 GB RAM to use the A300 primarly for Kodi and which will work stable and enough to run some (before) 2010 steam game ?

I was thinking this HX432C16PB3K2_16 , is it ok ? Do I need to configure bios to accept this module ?


Thank you

Deskmini A300 requires SO-DIMM memory. The smaller type found in laptops.
