INTERCHANGEABLE TOP AND FRONTThe best case in any situation
Whether you prefer a virtually inaudible or an extremely performant case: Dark Base Pro 901 is the perfect choice. Dark Base Pro 901 features a silence-oriented and performance-optimized solution for the top and the front. All panels are included, and a user-friendly mounting makes
switching a breeze.
MAXIMUM USABILITY
For professional and casual use
Dark Base Pro 901 offers all functions enthusiasts could wish for in a high-end case. Among them is a detachable top and front bracket with included fan hub and pogo pin connector for a comfortable installation of radiators and fans. Even an inverted layout can be done easily thanks to an intuitive rail system. Numerous cleverly integrated solutions make handling extremely easy. Dark Base Pro 901 can be deployed without the hassle of additional screws and small parts, creating the optimal case for any build.
SILENT WINGS 4 PWM FANS
3 pre-installed fans for maximum airflow
Features like the silence-optimized fan blades and the funnel shaped fan frame make Silent Wings 4 140mm a fan that makes no compromises between virtually inaudible operation and high performance. Its extraordinary air pressure significantly increases the cooling performance of
Dark Base Pro 901.
THINK BIG
Generous dimensions for radiators up to 420mm
With its remarkably large dimensions, Dark Base Pro 901 sets no limits on creativity. The front can fit a radiator of up to 420mm and additional fans can be installed throughout the case, even on the side panel.
FLEXIBLE VGA HOLDER AND CABLE BARS
For a neat interior
The VGA holder of Dark Base Pro 901 is very versatile and prevents GPU sag even with heavy graphics cards. 2 cable bars, one located inside the VGA holder and the other next to the motherboard tray, hide the cables inside the case. No matter how big or numerous the components built in Dark Base Pro 901 may be; with such clever features the result always makes a
good impression.
ARGB LIGHTING
And convenient features
Dark Base Pro 901 features ARGB lighting on the front and the PSU shroud: The lit-up areas are chosen consciously to ensure the case remains elegant with subtle illumination. The light and fan settings can be conveniently controlled via touch-sensitive buttons on the I/O panel. A wireless charger for Qi enabled devices perfectly rounds up Dark Base Pro 901.
TEMPERED GLASS WINDOW
A perfect view inside your PC
The high-quality, fully-windowed side panel offers a perfect view of the components inside your case. The window is made of tinted and tempered glass with black painted edges.

Way too small with very little stretch.
I ordered a size 4X to make sure they were loose enough. The ones I received are like a size 8 very small.

If you haven't switched to boxer briefs, you're missing out :)
Size: 11 Plus, Color: Microfiber - Colors May Vary
I figured I ought to provide a review, something I'm not prone to doing even though I often/always bank my purchases on item reviews, since I just bought me a second set of these underwear because they're just that good!
I bought my 1st set of these 2 months ago because I was on the hunt for some new comfortable underwear and omfort was my main criteria. Wasn't aware that I was dealing with some health issues that was causing a fair bit of internal inflammation, just knew that I had had enough of basically everything I had at the time because they were old, ratty looking and even my all-time favorites had begun feeling too... something... not exactly too tight, yet they just weren't very comfortable anymore either and I didn't need that kind of extra stress in my life. But. I'm a barely-makin-it domestic violence survivor.
Sure, I'm super proud to have gotten as far as I have in this world (considering that post-separation psychological terrorism and torture continue to thus day, 5 years after I broke free) but, by rights and family-rearing, I should be living in a whole different world right now... which is my way of saying that money is extra, EXTRA tight in my house...and yet, I still have "caviar tastes", ifykwim. Lol. And, frankly, neither I nor anyone else should have to scrimp on comfortable, classy-feeling, fashionable clothing no matter how small our clothing budget may be.
I was spurred to check out boxer briefs for women after reading about a few different women's favorite brands in the comments on soneones IG post (that must have been in regards to underwear, but heck if I can remember the details). So, off I went to scout around on Amazon to see what this "boxer briefs" business was about... desperately hoping that the term was not just a rebranding of those "hipsters" things.
I am 46yo, 5'10" (potentially closer to 5'11"... not something I care enough about to know for certain, lol) and, clothing size-wise, my whole adult life I have consistently been a 16-18/18-20, top to bottom, with a shape that seems some what apple-ish at the moment but has, in general, always been more hourglass than apple. Also it seems as if I might have rather freakishly high hips, lol... not really, but for reference, when it comes to pants or jeans what generally passes as "tall", usually a 33"-34" inseem, fit like ankle or cigar length pants on me. But evidently I don't just have long legs, no, this momma's body seems to also have one heck of a long, tall pelvis which I did finally measure to figure out for sure but, prior to that, I could tell based on the way that low cut underwear like bikini & hipsters, and any form of low rise pants, barely make it north of my low lying c-section scar location which, for those who can't relate, is basically at the top of my hooha or just at the point where my belly and my hooha meet. And because that point on my body is not even remotely close to my "hip" area such items basically fall right off my body unless they're super stretchy and I deliberately hike them up to my hip area which I put up with in my 20s and 30s, for the sake of fashion I suppose, but which was and is quite ungodly uncomfortable, and... basically... I am so over with "uncomfortable" anything (men included, lol.)
In both cases I bought size 11, though, if I'm being honest, I am certain that a 10 would have fit well, too. And who knows, a 10 might have been just as comfortable or even more comfortable than the 11... but, I didn't take bother taking the chance to find out when I ordered my second set because the first set (size 11) made me so unbelievably happy that they literally changed my views about underwear for life.
This whole "pants come off after work" thing or the memes about people working from home (due to covid restrictions) and not wearing pants never jived with me prior to having these boxer briefs, but now... omg... these things are super inexpensive and somehow still suit my somewhat "caviar taste" perfectly (have a good handfeel and are just so unbelievably super comfortable), PLUS... they're opaque and they basically fit (and look) like I'm wearing a loungy pair of bike shorts, so... yeah, I've spent some time over the last 2 months actually chillin in my house in my freaking underwear!!!!
Life. Changing. :D
