No airflow, too small for a "full-size" graphics card, much more 7/3/2020 3:23:13 PM

Pros: Cheap

Cons: Claims to fit up to a 300mm video card, I'd love to see someone install it. Mine is 243mm and BARELY fit, and can't use a 3.5" hard drive with it installed. That's the main reason I give it 1 egg, 300mm video card support is a complete lie, just because there is 300mm of space doesn't mean a video card can go there, there is also a non-removable panel (3.5" mount) that covers the ports

Absolutely no airflow, the front should've been a mesh instead of solid, horrible design even for a cheap case. Whoever designed it should be fired immediately.

Overall Review: I suggest spending a few more dollars and getting a case that's larger with better airflow, and easier to work in.

Great cheap case 6/5/2020 3:26:30 PM

Pros: I love this little case. Perfect for what I needed it for. Small form, light weight

Cons: cheap metal but that obvious for its price

Overall Review: I would recommend this case for anyone on a tight budget or just needs something now.

Bad Thermals, not for Gaming 5/24/2020 9:13:22 PM

Pros: Compact; Does not have a "cheap" look; Has a side panel window; back panel extends slightly for cable management

Cons: VERY small intake at front of case, on bottom, and gets smothered regardless of whether on solid surface or not; terrible airflow; cable management a disaster; unable to fit 3 fan GPU; oddly-placed standoffs; screws not labeled

Overall Review: When we began putting this together, we noticed the bag of screws with drive bays, Mobo mounts, and PSU mounts were all mixed up. I consider myself a PC enthusiast, so this was not my first rodeo, and let me tell you, I struggled to identify which screws were for mounting Mobo on standoffs. Guess what? I made the wrong decision, and the screws were HELL getting out as they caused the Mobo standoffs to turn in place.

Cable management? Haha. No. The only good part about this is the fact that the back panel extends out a little for the PSU cables, but the peripheral and front panel cables take up a lot of space, and block airflow.

Oh yeah, want to put in a modern GPU with three fan cooling like 5700xt, 1080ti, or something comparable? Not happening. The drive bay chassis blocks your ability to plug in PSU connectors.

After building, I saw that the front had a small, finger-width opening at the bottom. I sat the case on a desk, and heard the case suffocating and struggling to pull in air through the single-fan intake. Also, the only other fan in the case, the exhaust, is only 80mm and with the indention made for this, you could never upgrade without a modification.

IF YOU PLAN TO GAME, AVOID THIS CASE. Basically, we were running simple games like "The Forest" and "Subnautica," and this case was getting too hot. I legitimately was concerned the acrylic glass panel would melt or warp.

Cheap 4/7/2020 1:37:54 PM

Pros: Cheap

Cons: Airflow
Tiny Fan

Overall Review: Perfect for a basic workstation build w/ Ryzen 3200G and a budget B450 board. Temps are perfectly acceptable and it is quiet even with the included stock cooler. Easy to build in, though it is a bit tight to install the motherboard.

Decent for the price 1/6/2020 8:33:11 AM

Pros: - Has a 5 1/4" bay for disc drives which is becoming more and more rare even though some PC builds have to have one.
- Included 2 fans.
- 4 front USB ports is always a nice feature even if you rarely ever use them.
- Black interior with a more open concept design which has it's pros and cons but still a nice touch.
- A full size PSU fits nicely in the case.

Cons: - Biggest con is the lack of front ventilation (2 egg deduction for specifically that reason). If you buy this case, then you'll need to drill out small holes in the front panel to allow air to flow through. It's fairly easy to do as you can just use the existing pattern as reference and not negatively affect the overall appearance of the case.
- After installing the 5 1/4" drive and 2 1/2" SSD, there was no room for a 3 1/2" drive. In fact, I'm not even sure it's possible to install one at all even if the case was empty. Maybe I missed something?
- Cable management is more or less non-existant unless you have a 5 1/4" disc drive to tuck and hide the excess cables on top.
- Had to temporarily remove rear case fan to fit the motherboard in place (very tight squeeze), slight modification to the case would have prevented that.
- 2 of the standoffs were not installed and not supplied for the Micro ATX motherboard, the ones I added myself could not be tightened as the tread on the case was very thin and so the screw would just flop around loosely when it got to the end... not that it matters much as it's just for motherboard support when applying the 24 pin connector and ram, the welded ones supplied are more than secure enough for the motherboard.

Overall Review: Reason I bought the case was because the customer I built the computer for didn't care what it looked like as long as it was light and had a 5 1/4" bay, so I bought the cheapest one available that would work well enough for the build (and didn't look cheap or horrible). I knew about the horrible airflow before buying the case but could see that it was an easy fix to deal with and wouldn't ruin the overall look. I just didn't know I couldn't fit her old 3 1/2" drive which is weird and unexpected. Overall, I think the case is decent for the price and would consider buying it again for another customer. But I'd rather spend more money on a better quality case if purchasing for myself.

great size for a SLEEPER computer 8/29/2019 11:28:12 AM

Pros: perfectly sized for a MICRO ATX motherboard, and 1 cd/dvd burner....also great price, for what they give you in a case...its got 2 - usb 2.0 & 2 - usb 3.0 ports in the front

Cons: I didn't not(not) like anything with this case, its my 2nd exact (same)case in a year I have bought, the 1st went to my girlfriend, it still works perfect, hers is not a sleeper, but it does have 32 gigs of ddr3 maxed out

Overall Review: I would recommend it for anyone wanting to build a SLEEPER....the motherboard is gonna be a 64 gig ddr4 - -
