Chipset: Z890. I do not need all of its power, and do not really want to pay $300+ for the motherboard, but I also do not want to discover that something I want is missing from a budget motherboard (which are not yet available anyway).

Form Factor: Mini-ITX (170 mm × 170 mm) - let’s try something small this time :)

CPU: Intel Core Ultra 9 285K $630 from BandH; sales tax refunded

Motherboard: Mini-ITX (170 mm × 170 mm) (2xCUDIMM, 128) - Asus ROG Strix Z890-I Gaming WiFI Amazon $450 - Asrock PHANTOM GAMING Z890I Nova WiFi NewEgg $300 (got!; $319 with tax) - RAM: 9866+; 2xTB4, front USB-C - MSI MPG Z890I EDGE TI WIFI NewEgg $370 - RAM: 8600; 2xTB4, front and rear USB-C - Gigabyte Z890I AORUS ULTRA $350 NewEgg $560 - RAM: 9200; 1xTB4, front USB-C MicroATX (244 mm × 244 mm) (4xCUDIMM, 256) - Asus: none - Asrock PHANTOM GAMING Z890M Riptide WiFi NewEgg $260 - RAM 9466MHz+; 2xTB4, front USB-C - MSI: none - Gigabyte: 1xUSB-4

CPU Cooler: NH-D15 G2 $150 at Amazon AIO probably makes more noise, and Noctua passive cooler with one fan is probably not enough…

Case: aluminum extrusions: Yoqanr or egowz; see also BeamCase - and https://www.framingtech.com/ since:

  • DeepCool CH160/CH170 with mesh side panel - company is under sanctions
  • Jonsbo C6-ITX Black (PSU/cooler clash? does not really fit D15 cooler, although its specs list 168mm and the cases’s 170
  • LianLi O11 AIR MINI - does not fit the cooler

Got egowz for $53 at Amazon. Instructions: https://www.zwzdiy.cc/M/Product/24LHST/, more specifically: https://www.zwzdiy.cc/M/Product/3875925916.html.

SSD: Samsung 990 Pro 4TB $320 - preferably without the heatsink, so I can use the one on the motherboard (although model with heatsink is cheaper at $300). - got for $322 at Amazon

RAM: CUDIMMS 2x64 are not yet available; I can give up on CUDIMMS or buy something for the new build that I will stick into the previous desktop when CUDIMMS become available…

RAM in the 2022 desktop with the MSI PRO Z690-A WiFi motherboard: max 128/192, 5600 JDEC 6400+ OC; currently, 4x16 Corsair CMK32GX5M2B5600C36 DDR5 5600 MT/s 1.1 V $ sudo dmidecode -t memory 2x48GB:

around $1,855 without PSU

PSU Wattage:136-250-275-370 for CPU; 30 for motherboard; 27-37 for RAM; 9 for SSD; so, around 450.

PSU sizes:

  • ATX PS/3 150mm (W) x 86mm (H) x 140mm (D)
  • SFX 125mm (W) x 63.5mm (H) x 100mm (D); deeper for SFX-L
  • Flex ATX 81.5mm (W) x 40.5mm (H) x 150mm (D)
  • TFX12V 85 64 175

Flex/TFX are too loud with their 40mm fans, even Enhance ENP-8345L 450W Modular Platinum Flex ATX $140 at Amazon; 81.5mm (W) x 40.5mm (H) x 165mm (D).

So, SFX/SFX-L.
