Title: Very nice gaming PC
Review: This gaming PC is amazing in every way.The graphics card is top notch and works flawlessly with the motherboard, processor, and RAM.My use for this machine is multi faceted but mostly its use is for streaming and I have yet to push more than a 30% load at any given time running max graphics capabilities for streaming.The aesthetics are on another level with the RGB fan and RAM lighting, and the included program works great for dialing in exactly how you want your lights to display. (After updates it was necessary to re-install the ASROCK light program for proper functionality. Please ensure you’re downloading the correct version of the utility if you run into this issue as well. The updated version works great.)The fans are not very noisy and the audible noise output is what I would consider a medium level hum for PC fans.This PC is sure to impress anyone who’s into computers for virtually any use, and the price tag is low for how powerful and well functioning it is.For the reasons outlined in this review I give the Thermaltake LCGS Quartz i460 R4 Gaming Desktop my highest of recommendations! Purchase with confidence!

Title: Honest opinion (may update)
Review: Just got this PC a few days ago, so I will update this review if anything changes! But it was super easy to set up, and it came with really good packaging, the PC came in perfect condition. The computer has 3-4 fans inside and I have had zero issues with heating. It runs extremely well, I have had no lag what-so-ever.I have it set up connected through an Ethernet cable, but it can connect to the WiFi wirelessly as well. The build quality is amazing, love the LED lights— which you can change the color to!Downloaded my games very quickly with no problem! The sims 4, which used to take me forever to get downloaded, downloaded almost all the game packs and the main game within an hour and a half.For the first few hours of using the PC, it did have minor issues with using too much WIFI, but it fixed itself rather quickly (could have just been my provider).Overall, I have no complaints about this PC. I’m in love.

Title: My GF loves it!
Review: Bought this as a birthday present for my girlfriend and she loves it. She loves games like sims4 and her old pc couldn’t handle all the cc and mods. She’s loaded this new pc up with all the cc and mods she can find and it still runs flawlessly. Setup was quick. It runs real quiet and cool. Overall I would buy one for myself if I needed to.

Title: Good pc
Review: I have been using this pc for a while (8-ish months) and so far it has worked great! When I first got it it was very laggy because the graphics card wasn’t working but I took it out and plugged it in again and that fixed it. Overall a good pc if you want to start learning about pc’s but have no idea where to start. Not sure about how easy it is to upgrade as I haven’t done much of that but it is fairly good for its price.
