[T] Moving on to a test bench

A project log for Teti [gd0022]

A 3-in-1 desktop because I can't build a 2-in-1 laptop.

It's been almost 6 years since I started conceptualising and modelling this PC and almost 5 years since being able to use it while it was perched on the box the motherboard came in. Due to starting my #Hexagon Bed for a 220 cm Mattress project, I thought it was good to do some 5-year maintenance.

Since it's been 5 years, I can only come to the conclusion that I didn't need the portability I designed Teti for. Instead of 3 screens stacked ontop of each other, I've instead just used a single one of them in portrait mode for the past year. 

Since I hadn't used it for some time, I also disabled the Gigabyte Titan Ridge in Device Manager because I was getting a stream of Error 17 in Event Viewer where "A corrected hardware error has occurred." with it about 30 times a second. It obviously isn't advisable to route a PCIe wire right under the CPU of all things, and then flatten the weight of the motherboard on it:

The above was taken while I finally moved the components to an £11 test bench, which I got so that I could properly mount the PCIe expansion cards, not have the motherboard slide when plugging in/out ports and even get a power button! Yes, I've been having to close the circuit with jumper-wire and something conductive, such as wire snippers, to turn on the PC for 5 years.

The space on the left is in part because there is only an ATX PSU mount, not SFX, and because said SFX PSU plugs into a stiff 4 metre cable I bought for that portability I mentioned. The 3060 Ti is merely a few millimetres shorter than the test bench, so I think it's a nice fit.

For the aforementioned #Hexagon Bed for a 220 cm Mattress, I've been looking in a slightly larger, high refresh rate monitor with a small "chin" bezel. The only one that does all that without giving up touch is a Realza 18" 3840 x 2400 120Hz monitor:

I plan to go down from 150% on the 15.6" the UHD screen I use now to 125%, increasing my portrait logical resolution from 1440 x 2560 to 1920 x 3072. 

I looked in the documentation of the Titan Ridge and it supports full DisplayPort 1.4, not allegedly capping the framerate at 4K60 like the Vision D Z590I motherboard documentation claims. Using a bandwidth calculator, a little over 100Hz is possible without display stream compression; I've heard some NVidia features turn off when its in use, though I don't think I've ever used them. I believe monitors over 16 inches need a little more power than 15W, the minimum spec for USB-C ports. Since I already own the Titan Ridge, which has a 27W port that can inject DP into USB-C, the most seamless and lowest cost solution is to simply replace the old NVMe to PCIe riser cable with a new one for £8 (which is half I paid for half the speed 5 years ago):

I believe the power terminals are only for cards that need more than NVMe yet do not feature their own 12V sockets, which the Titan RIdge has.

This test bench has an oh-so-convenient set of cutouts to port it right on over:

This, and the lack of small cases that would support this, is one of the reasons why I got this test bench.

As for #Tetent [gd0090], it means there are no longer any sizing limits.
