Oh, I like where this is going. Gonna wait and see what you have success with and try to use a combo of it and the wireless hdmi grath recommended for my tv set-ups.

FYI the Chromebox is a reasonably established concept at the point, for a mini computer that runs ChromeOS but you aren't paying for a screen that you don't intend to use. That with some form of screen sharing app and/or booting Windows on them could be a serviceable option.

Oh yeah, already did that. Can't find the post just at the moment but I bought an old HP Chromebox on eBay, swapped out the SSD (and I think the RAM too), flashed it with Mr. Chromebox, installed Manjaro/GNOME on it, and hooked it up to an old monitor and speaker I wasn't using and set the whole thing up in my kitchen.

If you'd rather use Windows, there are a number of Chromeboxes that'll support that instead; see the same link I included above. (The HP model I've got is one of them; it's the i7 model codenamed Zako.)

Or if you're okay with ChromeOS, you can skip most of that shit and just stick with the original hardware running ChromeOS and use a screen-sharing app. I think ChromeOS supports Android apps now, though that's not supported on older machines so if you want to go the ChromeOS/Android app route you'll want to verify that it'll actually work on a given Chromebox before you go buying it.

I decided to roll the dice on a laptop described as simply "laptop" from a seller with zero feedback. Near as I can tell from trying to read a blurry photo of the tag, it appears to be an Asus L203MA. Which meets almost none of the criteria I stipulated in my earlier post, but at least it was cheap.

I think "spend a few hundred on a new primary laptop and use the C720 as my Windows machine" may still be a viable strategy, but I'm going to hold off for now.

I'm considering a Star Lite Mk III as maybe a new main laptop. I could probably get a similarly-specced Thinkpad for $100 less, but I'd have to make sure I could run Linux on it; I know Lenovo's had some issues in the past with locked-down EFI, and that's before you even start getting into drivers.

Okay I think this one's the hardware advice thread? I have an old ASUS RoG laptop that's dying by inches but is still my most powerful workhorse and gaming machine (seriously impressed by how gracefully these things fail) and the fans are on their way out now. Temperatures are getting near to triple figures and thermal shutdowns are looming.

Conveniently, it has a separate access panel behind the screen hinges which would allow me to bolt pretty much any arbitrary cooling system onto the tops of the heat sink fins (pipes are welded underneath) but I'm not sure what general approach is likely to have the best effect. A vertical fan CPU cooler on top of each heat sink, with maybe a copper plate clamped to the CPU one first? PVC plumbing and hot glue to divert the ports to a single outlet pipe with big ass fans on the end? Could Peltier pumps be useful here?

Can you replace the fans, and blow any accumulated dust out of the heat sink slots? Next best might indeed be using new fans over the existing heat sinks, directed into or through the slots. The fin edges wouldn't be great for transferring heat to another solid object.

Peltier junctions are rarely the solution for CPU cooling. They've only got on the order of 10% efficiency, so if you're supplying 10W of cooling on one side, now you have to dissipate 100W of heat on the other side. Handier if you need to get the cold side below room temperature in some device.

Replacement is a no-go without a serious maker lab, the few allegedly compatible fans are expensive, sketchy looking and don't deliver to the UK. I need to do something based on generic ones which means mounting them externally.

Okay: solid state devices are out, but these heat sinks seem to be built with a lot of flat surface connecting the blades across the top. Directly cooling those surfaces would be fairly straightforward, but maybe less effective than just suctioning a lot of air through the fins?

I'm already doing the latter for the GPU with spit and baling wire, so I guess it makes sense to try the other approach on the left and compare results. Nothing to stop me doing both at once either.

Still won't be as stupid ugly as the official watercooling dock.

Given that background, it's not entirely surprising that the seller never accepted my payment or responded to my messages. I just hit the 30-day mark where Paypal automatically refunded my money.

At least they didn't take my money at all; that's considerably better than taking it and not sending me the laptop.

Anyhow, it wasn't a great laptop anyway.

I went ahead and put Windows 10 on my Surface 3. I've been a little surprised by how janky the experience is; I thought the MS hardware/software integration would make for a much smoother UX, but I guess there's only so much you can do with a low-power processor and a touch UI bolted onto twenty years of legacy cruft.

Anyway, it'll run FF7, though it chokes a little on some of the spell animations (presumably because of the hi-res texture pack; I'm at least hoping it wouldn't choke on the vanilla version of the game). The important thing is I got through the fucking snowfield without any crashes. Tempted to switch back to the other laptop now that I've done that.

I'd still like to get another laptop. Whether I still wanna go with a cheap Windows laptop or go for more of a midrange Linux laptop and put Windows on my Chromebook, I haven't decided yet.

I don't expect that's a decision I'll be making right away. November's the month when home insurance, car insurance, and property tax are all due at once.
