After a year of obsessing over different itx builds and planning different configurations for multiple cases I finally decided to downsize from my 14.6L matx case down to an S300 with almost all used parts.

230 - 7500X3D, 16gb 6000mhz, msi b850m (Microcenter) Sold the matx board for 70$ from the 300$ bundle.
20 - Thermalright AXP90 X36. (New)
75 - Asrock A620i lightning. (Almost new)
100 - RTX 2060 super 8gb.
20 - 2TB seagate slowass laptop hdd (cuz 2026)
80 - Corsair SF750 old version + free RAM cooler.
60 - S300 white. (Unused condition)

Total 585$

Pretty much everything, except the 7500X3D Microcenter bundle and the cooler, was bought used from Facebook marketplace.

The size difference going from 14.6L to 8.1L wasn't as big as I had initially imagined but nonetheless I'm really happy with the final build.
Sold the matx case, matx mobo and atx psu to switch to the S300.

The 2060 super is a bottleneck but I couldn't afford anything better at the time when I built the matx PC. Still, it serves me well in 1080p.

I was eyeing the gigabyte a620i for 110$ brand new, but that thing had only 1 m.2 slot. The asrock has 2 slots so I couldnt resist buying used for just 75$

I know I could've gone for an X53 or IS55 but it's just a 65W cpu and I wish to put these parts in a 4 liter case in the future when I upgrade maybe 4 years from now.

The RAM cooler couldn't fit in the case so I took the fan and wedged it in the gap to be used as SSD cooling.

I used a random Chinese 128gb nvme gen 3 SSD and a 256gb kingston sata ssd that I carried over from my old PC in Bangladesh.

Cable management was a huge pain. As I had never worked in a case this small before, every touch felt like I was about to break something. But after spending a couple of hours routing cables I had a good sense of where each cable should be. The biggest challenge was using 2 separate sata power and data cables for the ssd and hdd and hiding them cleanly. There's a big bundle of cables under the gpu side but that's unavoidable because of the 24pin atx cables and excess sata power connectors.

Overall I'm really proud of myself for how the final product turned out. Just need to save up for a good GPU like a 9060XT and I'll have a capable 1440p lunchbox machine.

This thing is 14.6L, a whole litre smaller than the Ncase M2. Yet it fits a mATX board and ATX PSU.

CPU cooler max height is 135mm.
Supports GPUs upto 335mm (according to specs, but my 2060s is like 270mm and going any higher would block atx psu cable management.)

Bought it on Amazon for around 55$ with no when it was on sale. Case has no name however. To my understanding, it's a modified version of an SGPC K88 (last pic), with front airflow but I'm guessing less rigidity by comparing the reviews.

Cable management is a struggle though. It is guaranteed that you will have to block a bit of the gpu airflow to tuck the 24pin and pcie cables underneath.
However since it is matx, there is guaranteed enough space under a 2 or 2.5 slot, maybe even 3 slot gpu, to fit regular width fans underneath and still have enough gap for airflow.

Fan compatibility is just 2x120 / 3x90 on the bottom.
2x90 / 1x120 on the top, and 1x90 on the rear.

Overall visual design is nice with the glass panel. There's an included orange handle which I don't use because the panels are kinda flexy. I wouldn't trust this thing for portability at all. The rivets and joints bend physically when I gently lift the case up from the bottom, due to the weight of the ATX psu. Decent case if you want desk space but don't want to spend extra money on ITX parts, and don't need portability.

Good alternative to an 18L nr200p in my opinion, if you have a smaller gpu, 65/105 watt cpu and a relatively lower budget.

This was my first proper pc build. For a long time I dreamt of going the ITX route with an A4 H2O or S300, but with insane prices and financial struggles, I decided to go for this case and the 300$ 7500X3D bundle from microcenter.

Now that I have a job though, it is tempting to sell the board and psu and case then buy used parts to go the S300 route.
