My 2020 upgrade to Schwarzgerät, built around the TRX40 platform. This will be an upgrade of cooling, motherboard, CPU, and RAM; I'll continue making use of my current case (CaseLabs Magnum T10) and SSDs/disks. This will be my first liquid-cooled machine, and I am likely to go for a custom loop. I would have just used a Noctua, but their only product designed for the sTRX4 isn't available in chromax.black. I'd deeply adored Noctua chromax.black for months, and its lack of availability for this build (plus the 3970X's awesome 280W draw) made me say "fuck it". I'm going custom loop due to the paucity of 360mm AIOs for sTRX4.

Boldfaced components are definites.

Role Component Reasoning Cost/Vendor
CPU AMD 3970X One of the finest packages of our era, at a fantastic price point. Thrashes the 3990X's 2.7GHz base clock with a 3.7. I furthermore believe the 64-core 3990X will be memory starved for most task sets large enough to engage all its cores, and thus not worth paying double (it's still an awesome chip). $1950 Amazon
Motherboard Gigabyte TRX40 Aorus Master Unlike most of the TRX40 boards, it has a fifth 1x PCIe slot, and I always find myself with the occasional piece of shit I need plug in there (usually some wireless card). 1 slot's holding a GPU, 1 slot's holding a SAS card, and figure the other 2 are occupied with 10GigE and/or Fibre Channel and/or a massive SDR and/or an NVMe expander and/or accelerator. Those $850 motherboards couldn't spare a buck for a fifth PCIe slot, even at Gen3? Lame. I have 10GigE cards falling out my asshole, so I don't need them onboard, or at least don't need to pay a premium for it (though that does free up a PCIe slot, depending on what I'm doing). The Aorus Master does, however, give you 2 ETH PHYs (1 Aquantia 5GigE, 1 Intel GigE), and I can always use more of those. It's got the big beefy 16+3 Infineon VRM solution of its pricier brethren and the same Intel AX200 2x2 802.11ax wireless. It doesn't ship with a Thunderbolt card or an NVMe expander like pricier ones, but I already have those, and have yet to work with a Thunderbolt device anyway. USB-C 3.2 Gen2, good good.

The only thing that worries me is that the audio solution is said not to work on Linux. I'll be using a USB DAC in any case, but if they botched Linux support there, where else might it be broken?

$500 Amazon
RAM
CPU block EKWB EK-Velocity sTR4 Nickel+Acetal The "Full Nickel" sounds alluring, but so far as I'm aware, full nickel doesn't improve thermal characteristics (the heat-conducting area is of course metal), so the extra $30 is just for aesthetics. I'd rather the top be black in any case. Acetal is reportedly less brittle than plexi, and is the correct color. I might get the D-RGB variant, as it doesn't add much cost ($10), and that might be fun to play with. The EK-Velocity line seems the canonical choice for sTRX4/TR4 waterblocks. $123 Amazon
