Some photos of my build. Need to add in another 8Gb RAM and fit handle and power button, but final spec will be:
M69 case + PCI-E riser + 450W PSU = £120 approx after all parts, shipping and tax
Asus Prime H310i-Plus R2.0 = £40 (2nd hand, Facebook Marketplace)
Intel i5-8400 (Hex core) = £92 (2nd hand, eBay)
Noctua NH-L9i = £35 (new)
RAM = 16Gb DDR4 Corsair LPX 3000 = £47 (2nd hand £15 + £32 new)
GPU = AMD R9 Nano 4Gb = £80 (2nd hand)
SSD = SK Hynix 256Gb NVME= £30 (2nd hand)
Total cost of £444
Running Prime 95 and MSI Kombuster concurrently for 10 minutes with no additional case fans, the CPU reached 65C and the GPU 75C. This is both at 100% load. PC was audible but acceptable for such a small system. At rest it emits audible noise, but it's acceptable. I will record some videos tomorrow and post so you can hear the noise levels for yourself
This has been the easiest PC I've ever built. I was gaming inbetween building, but i reckon I could have had this fully assembled and booted in around 35-40 minutes.
83 on 1080ti mini. (With nf-a9x14 fans attached to stock shroud)
62 on cpu.
I also have 3 40mm noctuas in my case.
Zotac 2070 Super Mini is the most powerful I can think of in 2000 series. No idea on 3000 series so will need to wait on official announcement firstso whats the next GPU in 2000 or 3000 series that can fit this case? while the 1080 TI is good its starting to get old =)
