Okay, let me first start with that the cable management in this build is atrocious... and because of that I'm showing it to you so you should know what you should or shouldn't do with it. Could it have been better – yes! Could it have been worse - hell, yes! It is what it is and I hope it's helpful for you. Anyway...
I build this PC just for the fun and because I got a faulty mATX motherboard for a good deal (that somehow I
manage to fix partially)
So I've never build before in a mATX case and I knew it's gonna be a challange for me with the cable management, so I decided to go for it.
If you're interested in watching the process and the parts I chose,
check out the video in my channelSo, the case of choice is Deepcool Matrexx 30 - probably the cheapest tempered glass case out there. It's small, very lite weight, it's nice looking and... with a poor cable management support. Mostly because the backside panel it's not much deep and can't fit almost nothing. And if you're using extension cables like I did... well... It won't look pretty. So, my advice for you is to not use such.
The motherboard is Asus Maximus III Gene. Got it for a good deal, managed to fix it (at least the main problem with the BIOS). It's semi-premium board from the ROG series 10+ years ago. $30 USD is pretty cheap for a board like this + additional $10 for the BIOS chip.
The CPU is Xeon X3440. No additional words needed for this CPU. Overclockable with 4 cores and 8 threads for $7 USD is crazy.
The cooler is be Quiet! Pure Rock Slim. I went with that because the case supports up to 151mm height of the cooler. For the lite overclocking I went it's decent enough for a cooler with 92mm fan.
16GB of DDR3 memory with added black & red heatsinks.
The graphics card is XFX R9 270X Double Dissipation. It still decent for most of the games and some triple-A titles with low settings. It fits perfectly with the other components.
So yeah. It took me less than 1 hour to build it and more than two hours to cable manage it and this is the final result. Still I manage to sell it for a good +80% profit after less than 12 hours of publishing the ad, so I'm happy.
