Iv owned this pc for over 2 years now I can play rust and cod with no lag or latency it's silent for the most part. Can't hear it unless the whole house is silent and then it's a lil hum. Now this pc is classified as a mini/small tower, not to heavy either. Now I will suggest you get an external ssd drive the pc only has 1t of memory and it's eaten up quickly because there's not a hard drive in it so everything goes on the ssd. ... show more

Size: 5800X | 3080 | 32G
First off I think its important to note that there isn't a ton of updated information about these so I'll comment on the whole package. Case: I like the style and is why I went this direction. Building myself over buying it would have saved me about $500 but thats the current market and obviously liable to change. The case does look good but quite honestly, I figure $110(case by itself) should get you more quality as the case is rather flimsy. Especially when you consider the overall cost of the system. GPU: Mine came with the 3 fan Asus Strix GPU 10GB and is a LHR card. It's the card I wanted and the case has full RGB though I only care about blue. Really feel lucky to get this GPU though its just the one I wanted and not necessarily the best one(idk) Cooling: Case has (2) 120mm fans(1 up top connected to AIO rad and the other at bottom) and (1) 120mm fan at the rear. Bottom of case is entirely pass through with a large dust filter and was pleasantly surprised by that as I knew they added some perforation there but wasn't exactly sure of the set up. Temps: PC runs FAIRLY cool but runs about what is expected given case size, AIO size, and only room for 3 fans. Adjusting warzone settings slightly gives me a regular temp of about 75c though if I bump it to ultra and high on everything, I can tag 90c but didn't game there long to see if it would come down. Adjusting the fan curve here will likely help a bit. I run at 1440 and have frames limited to 100 and it doesn't even care i'm gaming really. Going from an Asus zephryus ga503du with 3750H and a 1660ti max q this thing is a monster. Assembly: Only thing that was loose was the rgb for the cpu cooler and it probably came off when I was pulling the stuffing thats inside the case. Case wiring was done nicely in my opinion. Setup: I was able to get a wireless keyboard and mouse to connect (had dongles for each) to aid in setup though I was hesitant it would work. Other than that, it auto installs windows on boot. I'll have to go through and make sure the BIOS is updated but that beyond this review. Overall: Its a lot of money to spend, but it's a lot of PC without having to worry about shipping, parts compatibility, and quite honestly, if you aren't looking for the cheapest price for each component then the price difference will shrink. Obviously the most expensive part of the pc is the graphics card and right now, at best a 3080 is $1000 at microcenter if you have one nearby. I could have built it slightly beefier with a 5900x and a 570 mobo and probably a 2tb m.2 but I don't really have time for ordering/waiting/dealing with shipping/ and returning doa components. Hope this review helps and I'll update as time goes on. I haven't even had it 24hrs is why the 4 stars instead of 5. Update: The fans that come with it are TT-1225 (thermaltake) 120mm fans. I am planning on upgrading to 140mm for all three with higher cfm to hopefully get better gaming temps. After under volting the GPU with MSI Afterburner, I now get max 70c at 1440 144fps and high setting throughout in Warzone. Beautiful. ... show more

Weirdest looking little computer I ever saw. It's cute. Unfortunately, it crashed to desktop after about 5-10 minutes in every graphically intensive (at ALL) game we tried on it. I did check for driver updates and all that and the thing is that unless something is actually broken in there--a bad piece of hardware--I could most likely have fixed it. But. I did not pay this kind of money for a computer so that I could spend the next few days messing around and tweaking it to get it to run right. It's a gaming computer. It should run games. Period. Sent it back and ordered another---DIFFERENT computer, one that actually looks like a computer this time (not that that matters,) for very nearly the same price but actually better specs. It's an Alienware but wth, right? This one runs games and hasn't crashed. ... show more

Arrived unable to boot. Manufacturer recommended replacement through Amazon. Amazon refused to send a replacement and told me to go through the vendor for replacement. The vendor replaces by refurbishing the defective unit and sends the same one back. I didn't pay full price for a new computer just to end up with a refurbished computer so I opted for a refund. Incredibly frustrating experience. ... show more
