    Gaming on a 25 YEAR OLD Laptop!!

    The line printer ("parallel") and serial ports on the back... wow... And USB came about in 1997 and support was available with Windows 95 OSR 2.1. The retail version did not have that, not even a service pack to add it. Windows 98 had it in the Retail version of Windows. Linux didn't get USB support till much later... I want to say the 2.4 kernel had it built in. I remember patching a 2.2 kernel to get USB support as there was someone who extracted the USB support from the 2.3 "in development" kernel for patching to 2.2 - worked pretty well, too. And you apparently forgot that hot-plugging a PS/2 mouse is actually a bad thing to do. Not unless you like replacing fuses on mainboards. And yes, I'm speaking from experience on that.

    What Happened To Laptop Docking Stations?

    They block the underside of the system, and the designs of some also blocked some airflow out the side. Meaning the laptop ran warmer than normal when docked. My current laptop is an old Lenovo W520. My current work laptop is a W540. I hate the docking station for the W540 (don't have one for the W520) because it blocks a lot of the bottom of the laptop and half blocks the side radiator exhaust as well when I have it plugged in. Meaning the fan screams when the CPU is under load.

    Nvidia Said We Couldn't Game On This...

    Don't completely discount it's use as a compute card, especially for distributed computing via Folding@Home and BOINC. I'll have to keep an eye out for some of these down the line.

    New Mass Storage Server

    Okay... let's talk about the chassis a second. Do you want hot-swap bays? Where will this system be living - in a rack, on a desk, where? How many drives do you foresee using, and how many are you starting with? Do you already have a chassis you intend to use for this, or are you building from scratch? On hardware, I'd say to go with an AMD FX processor with a 990FX mainboard to get as many PCI-E lanes (40 available) as possible for the least cost. This will allow room for a SAS controller (much better for cable management, especially when you get up to 8+ HDDs) and the 10GbE card. Most should have a PCI slot as well, so you can use that for the GPU - not like you really need anything powerful for a NAS. At the same time, as @8uhbbhu8mentioned, GbE limits you to about ~100MB/s maximum transfer to and from any of the connected systems. So if speed is a requirement, you'll need to upgrade all of your systems to use 10GbE.

    Going without radiator fans?

    Turbulence is going to be your primary issue here, as you've already discovered. Your expectation of the air direction after sealing off every other possible avenue of escape is unlikely to mirror reality. Having exhaust fans is about directing the airflow in a particular direction. This would work as expected if convection could evacuate the air at the same rate it was flowing into the system. If air is flowing in faster than it convection can take it out, you're going to have turbulence circulating the air in the system with little of it actually leaving until it has nowhere else to go. This is why it's important to have exhaust fans directing the airflow where you need it to go, as well as provide enough static pressure to push it away from the system so it doesn't get circulated back in via the intake fans. In your instance, you're not going to get away with no fans on the radiators or pointed toward the radiators. That's the only way to break the turbulence and exhaust the heat in a standard computer chassis. The only other way to ensure little turbulence would be a fan configuration similar to what's in a rack chassis, in which you have intake fans blowing a channel of air across everything, with it all going out straight through the opposite of the intakes. Since all the air is flowing just in one direction, any turbulence that forms is quickly broken and doesn't result in heat soak unless the fans are weak. In a typical desktop chassis, the intakes are at the front (and bottom), exhaust at the back and top. So even with just front-only intakes, you shouldn't get heat soak provided the fans have enough airflow to replace the internal air fast enough. Exhaust fans can further help prevent the heat soak by giving the air direction to flow and help with replacing the internal air. With what you've described, you're creating a lot of turbulence inside the case, leaving the air and heat inside the chassis with almost nowhere to go. Again you're not going to be able to get away without exhaust fans, since you need to give the air direction to flow, especially when you have intakes flowing in from all but one side.

    Intel Killed their OWN Product Lineup

    I picked out one sentence that I knew to be an incorrect statement and called out ONLY the incorrect statement. It speaks more about you that you're insinuating I'm taking that one statement as your entire argument when I at no point made any statement even implying such.

    Intel Killed their OWN Product Lineup

    The statement I called out from your original post was only about programmers, in which you said that we "have a hard time to utilize 4 cores or more from a fairly old Core i5-2500k". I'm not talking about those running Microsoft Office or who "barely know what email is". And I wasn't responding to anything else outside what you said about programmers, nor was I trying to say I'm a "typical user".

    Intel Killed their OWN Product Lineup

    Software engineer here.... We don't have anything like a hard time trying to use more than 4 cores. Though it highly depends on what you're doing. For example, i7-4xxx laptop my employer issued me... I have no trouble utilizing all the cores that provides. Especially since Visual Studio's compilers have supported multi-processor compilation (both through the compiler and msbuild) since at least VS1010. On one of the projects we build at work, that feature alone makes the difference between a 10 minute build and a 30 minute build on a quad-core build machine. And if that build machine had 8 cores to it, the build would likely take around 5 minutes, depending on how quickly Azure DevOps advances the tasks. Plus a lot of software engineers run VMs alongside their IDE to have a clean, isolated testing environment. And you need cores to be able to do that, along with a lot of RAM.

    Intel Killed their OWN Product Lineup

    AMD's FX chips had ECC support as well. In my NAS I have an FX-8350, which is very overkill given it sees less action than a computer nerd at a porn convention. But that's what I already had, so I went with it. The advantage there was having a mainboard/processor combination that already supported ECC, making it perfect for a home NAS, since it has the same memory controller as in the Opteron processors. The higher PCI-E lane count of the 990FX also has an advantage here for putting in multiple high-line cards - I have a SAS controller and 10GbE card in that system - but I digress. The Opterons, by contrast, support Registered ECC RAM. And their FM2+ processors also did not support ECC at all, but it was largely unnecessary since it was an entirely consumer processor. So for AMD to keep the ECC support with Ryzen out of the box I would more expect. That the Opterons and FX processors were sharing the same memory controller and processor architecture technology - with slight changes for the Opterons for the server market - allowed them to keep costs lower. And with Ryzen they've got to be keeping with the same pattern. Which allows for a simplified design and manufacturing, a simpler product launch, and lower cost. LTT has been lamenting about Intel's product lineup since their first reactions to Ryzen started hitting the market. And now it's time for Intel to figure out how to scale back and simplify their product lines. Since that is also where AMD has an advantage. Intel might even start closing the price gap as well if they do this.

    Was Windows Vista THAT Bad?

    Ah Vista. My experience with it was on a laptop I was issued by my previous employer before Windows 7 came out. I'd previously tried Vista thanks to an MSDN subscription I had for a short time, giving me access to betas and an early release copy of the final build. And I never had issues with it. I stuck with XP on my home systems merely because I didn't see a need to upgrade away. Plus the different "editions" of it was confusing at times. When "Weven" became available, the company's IT department offered everyone an in-place upgrade. Just download it, install it, and you're golden. In theory, at least. I refused to take the upgrade, in large part due to my experience with in-place upgrades in the past. I always do a clean installation with Windows. With the free Windows 10 upgrade, initially that was an in-place upgrade merely to get the system registered with Microsoft's servers, then I wiped the system and installed it clean. And when my current employer offered an in-place upgrade for Windows 10 for my Windows 7 laptop, I again refused it. My teammates at my previous employer, though, knew I wasn't taking the 7 upgrade. A few had asked, and I said I wasn't doing it. So in a bid to convince me to do so, several of them (thankfully not including my manager) made it a point to ask me periodically if I'd upgraded to 7. Then when I predictably answered No, they'd explain all the ways Vista had crashed or blue-screened on them, basically doing whatever they could to get me to upgrade to 7. I'd just shrug my shoulders. As I'd never had a problem with Vista, but I previously had issues with in-place Windows upgrades, I had more incentive to NOT take the upgrade to avoid any significant downtime. If I'd run into any issues with the upgrade, I'd lose a day of productivity trying to get it figured out, or needing to have IT re-image my HDD back to Vista or install Windows 7 clean. Windows Vista was Windows 6.0, showing the major changes from Windows 2000 (5.0) and XP (5.1). But given that Windows 10 is merely Windows 6.3, there obviously haven't been any major enough changes under the covers that warranted Microsoft to bump the version number.

    Copper Tubing is HARD

    There are several techniques that can be used to straighten annealed copper. I've used the tool that you showed that uses wheels on all four sides. It won't get it perfectly straight, but it does a pretty good job. I've used it to create straight tube runs in a prior build. Another technique is using a vice and hammer. Basically you clamp one end of the tubing into a vice, clamp the other end into vice grips, then (being careful) use a hammer or mallet and strike the vice grips a couple times. Also works quite well and is much faster than using the straightening tool. Only downside is that you're sacrificing several inches of tubing off what you're straightening. Works well on thinner tubing, and I've used it on 1/2" OD annealed copper before I discovered the straightening tool. As an alternative to straightening it, you can use 90-degree F-to-F or 90-degree hardline-to-hardline fittings.

    Cheapest RAID solution please!

    There are all kinds of RAID enclosures available with various connection options: eSATA, USB3, Thunderbolt. Look into what's available in that route before stuffing HDDs into your chassis. Mediasonic is one brand I've used in the past without issue, and they have an 8-bay option available for around $230 on NewEgg, or you can go with a 4-bay option. Other brands exist as well, so look around.
  13. There isn't consumer demand for it. That's why we don't have anything faster than 1GbE in most home network setups. It just isn't needed. It'd be a different story if home Internet access bandwidth was in excess of 1Gb everywhere, but that isn't the case. And having multiple computers connected to an Internet connection is generally the only reason most home networks exist. And most of that is wireless.
  14. You'd likely be surprised to learn this actually isn't.... new. Like 10GbE and IB, it's been around a while. It's used primarily in computing clusters, though. Right now they're looking at TbE. Yes, 1TB/s Ethernet.

    We got a $5,500 TAPE DRIVE!

    And a slight correction to what you said about the tarball. You didn't need to "wrap" the files in a tarball before writing to the tape. You instead used tar as the intermediate command: "tar cv [path/to/back/up] | [command to write to tape". And a similar command to reverse it. Provided the command to read and write from the tape could use the stdin and stdout streams. On Unix, you'd probably just be reading from and writing to the device interface -- e.g. "tar cv [path/to/back/up] > /dev/tape01". Definitely not as neat and clear as what you're doing, though.
