  1. Christmas is coming up and I'd like to buy myself a new monitor. Last night I tested my reaction times (humanbenchmark.com) on my ASUS PG279Q 144hz and my Samsung UE590 60hz 4k monitor. After about 30 tests on each monitor my reaction time was TWICE as fast on the 144hz panel. When using the 144hz monitor I'm seeing enemy's on my screen a full 0.1 seconds faster than my 60hz. That's an incredible advantage over players with 60HZ panels. I'm looking forward to testing the 240hz to see how much my speeds improve. I realize it won't be as drastic as 60hz to 144hz. If any of you that have multiple monitors with different refresh rates feel free to post your results here. Just wondering the average variance in reaction time between different refresh rate panels. I used humanbenchmark.com because they seem to be the standard for reaction time testing. Now my main question is which one (KD25F vs. XL2456) is better in terms of gaming performance? or what would you buy? Aorus KDF25F BenQ XL2456 Pretty much all the youtube reviews say that the Aorus KDF25F is a better monitor and has a slightly faster actual response time when tested. I just don't understand why the BenQ XL2456 is the overwhelming choice for esports gamers when the KD25F is $100 cheaper. Maybe it's cause the KDF25F is newer it's not as wide spread? I'm open to other choices of high performance monitors as long as it's 240hz. I would like to stick around $500 though. Thanks Mike
  2. I don't mind the look of his too much. The 90 degree fittings make it look good considering its a mini wc build.
  3. Water block for the GPU because it looks dumb having just the CPU cooled with rigid tubing.
  4. Magnets are a good idea. It would be harder for me to make but it would be a more premium option for firctionless movements. It would take some trial and error getting the right strength of magnets. The mouse would only need a thin sheet of steel over the bottom with a hole for the laser. I'm gonna go ahead and start making the air hockey style one just for fun. I'll use adhesive to mount a real mousepad on top of a sheet of 1/8th" plexiglass. Using a mill I'll add the perforations through the plexi/mousepad top. Once the top is done I can mount it to the top of air tight base also made of plexi. I have a bunch of aquarium pumps for the air supply. I doubt those will work though because more air pressure might be needed. I need to do some more research on air pumps. I'm sure I can find one for cheap that will work. I'll post some pics when it's finished. Shouldn't take too long to make with exception of milling the perforations. Times like this I wish I had a CNC.
  5. I wondering your thoughts on a "air hockey" style mouse pad. The mouse pad would be perforated to allow air flow, essentially turning your mouse pad into a mini air hockey table. This would in theory provide near friction-less mouse movement along with giving your hands some cool air flow as well. The only potential downside would be noise from air exiting the perforated mouse pad. If you were using headphones it might be none issue. Have any of you seen something similar to this? or have any thoughts about it?
  6. I have recently put a desktop PC in my shop which is not heated. This computer is air cooled but it got me thinking... Has anybody left a water cooled computer in frozen temperatures for an extended period of time? and did anything break? I imagine AOI with rubber tubing could probably withstand below freezing temps?
  7. I've always wanted a portable PC for extended trips. I really like this Lian Li Q37 Mini ITX case. I would like to mount a display in the location below on the opposite side of the glass panel. Does anyone body have the dimensions below? I'm curious what size monitor can fit that rectangular area? This is a 5x3" monitor. I'd like to fit the largest I can. (The picture below is not to scale.) I'd like to connect it directly to MB using HDMI to USB 3.0 cable or something of the sor. https://i.imgur.com/dkNZqbq.jpg Can anyone with this case take these dimensions? The components will look something like this. It should be around $3,500 w/ CPU/GPU water cooling and rigid tubing.

  8. About 10 years ago I had an 8 camera CCTV system w/ DVR wired through my home. I'm considering expanding my system and would like to know how you guys would put something like this together. I plan to have new cameras feed into a PC rather than a DVR. I've been researching the best BUS and how to connect that to the pc. It appears that "Power over Ethernet" is my best option as it provides both power and a high bandwidth. Would a POE switch like this work? And does all 16x camera data travel back to the PC over one ethernet port? https://www.newegg.com/p/N82E16833122991?Description=POE switch 16&cm_re=POE_switch_16-_-33-122-991-_-Product Do you think a Dell Optiplex with i5, 8gb ram, 1tb HDD be able to handle a 16x camera system? Or is better hardware needed? It's my first time setting up a system like this so any advice is appreciated Mike
  9. I saw this on NewEgg right now and though it might be a good deal and reviews all 5 stars. It's much cheaper than your budge though. https://www.newegg.com/p/N82E16824025512?Description=4k IPS&cm_re=4k_IPS-_-24-025-512-_-Product There are two main types of panels. TN and IPS. The TN panels are generally cheaper, have worse color accuracy, worse viewing angles but higher framerates than IPS panel. So you probably are looking for a mid to high end range IPS. I'm not up to date on current models so hopefully someone else will chime in. If you haven't yet make sure your GPU is powerful enough to get a stable 60 FPS. My 1080ti works well for that but my 980 would often get 40 FPS in 4k gaming on demanding games.

      Don't use userbenchmark.

      Whats the best whole system benchmark? I only have experience with Unigine Heaven and CineBinch for CPU. 

       

      The only reason I tested it last night was to see the overall performance difference between the three machines I have. An Optiplex 390, brand new NUC w/ I7, and my gaming rig. 

  11. I was thinking space might be a concern. I just did some math and measurements just to see what it would be like. A glass sphere that is 3"(7.62cm) in diameter has a volume of 7.83 ounces. For reference a Red Bull can is 8 ounces. That should be enough fluid more most peoples rigs. These are the measurements on my own rig (x99 deluxe, stock 1080ti and all ram slots full.) There is 3.25" distance starting from the top of the ram to top of the GPU. The 3" sphere would not stick out past the GPU and you would have .25" of gap between the RAM and reservoir. All should be good in terms of fitment unless you have abnormally tall ram. Living in a cannabis legal state I would think it would be fairly easy to find a glass blower to make this for under $50. The only issue I see is that the glass blower could only make it work for compression fittings or glass on glass style fittings. I have a mill so I would probably cut and shape a piece of acetyl to mate to the glass. That way I could drill and tap the Acetyl for the standard G1/4"
  12. I personally would get the 9900k. It's a better CPU for gaming imo unless you need the extra cores on the 3900 for workstation stuff.
  13. Pretty much all the water cooling reservoirs I've seen are either plastic/glass tubes or fit in a drive bay. What do you guys think about a spherical reservoir? I imagine a 3" glass sphere reservoir would give a pretty neat aesthetic and function equally as well. Also that pearly colored fluid some people use in their rigs would probably swirl nicely due to the shape of the sphere. I did some google searches and it seems OCool had a prototype of something similar made this year. It looks very wild and RGB. In my opinion a simple glass sphere would look a lot better. So what are your thoughts on a sphere reservoir? Would it work aesthetically and function equally?
  14. Yeah it's a mini tower. It looks just like the 790 but the io is a little different. The connections all look like they will work. I thought I remember reading some people had trouble fitting a normal sized PSU in the mini towers. If I had an extra ATX PSU I would try it. I think I might order the SFX because I hope to make mini ITX build in the future and could salvage it from the optiplex build when I'm ready. Thanks, I skimmed the whole article. I didn't know that the older Dells could be fire hazards due to weird OEM connections. I think my Dell is a "newer" one. IT came with Windows 7 from the factory. I think it was built in '07 but I can't confirm if that's what the factory sticker numbers mean.
  15. Sorry I should have checked. I assumed the Optiplex PSU would be like my AX1000 in that there would be extra molex connections on the PSU. It's just a single wire harness with no extra connections unless they are inside the casing the PSU which I doubt. I guess I'll just have to wait then for the SFX PSU. Thanks for your time. Mike
