For those who’re planning to construct a brand new gaming rig in 2021, now we have unhealthy information for you—that is going to be tough to inconceivable, because of provide chain constraints imposed by COVID-19. However we even have excellent news: whilst you may not have the ability to construct a gaming PC, you possibly can virtually actually purchase one.
Do not get us incorrect. When you’ve got sufficient time and persistence, you possibly can nonetheless amass all of the elements to construct your personal customized rig from the bottom up. However that would take weeks and even months at this level in 2021. So as a substitute of choosing elements lists, our subsequent System Information will deal with current rigs from three of the main pre-built gaming PC distributors.
HP and Lenovo offered us with an Omen 30L and Legion 5i Tower, respectively. We additionally wished to overview an Alienware Aurora R11—and though we weren’t capable of get a overview unit from Dell, Senior Commerce Editor Jeff Dunn graciously took just a few pics and ran some restricted testing on his private R11.
Even on the massive OEMs, the {hardware} that’s obtainable at the moment modifications from week to week. However armed with part efficiency charts and a radical overview of those methods, you can also make your personal well-informed shopping for selections.
The contenders
-
The Legion 5i (left) has a a lot bigger rear exhaust fan, which helps contribute to its usually decrease noise stage. We additionally admire the carrying/lifting area of interest above that enormous fan. The Omen (proper) has an additional pair of rear-facing USB ports.
Jim Salter -
The Omen (proper) is somewhat nicer to have a look at from its clean aspect, which is not bothered with the horrible sticker-itis the Legion (left) suffers from.
Jim Salter -
The Lenovo’s matte end (left) requires plenty of obsessive damp-rag-wiping to maintain pristine, which I clearly failed at even in its first half hour out of the field.
Jim Salter -
That is Senior Commerce Editor Jeff Dunn’s private Alienware Aurora R11.

That is the highest view of the Alienware Aurora R11.

HP Omen 30L
The HP Omen 30L and Lenovo Legion Tower 5i are mid-tower systems, a little on the large side but nowhere near “full tower” bulk. Each is significantly heavier than you’d expect from its size, but these machines are still well under anything you’d want to slap a “team lift only” sticker on. The Omen is slightly larger, but the Legion unfortunately makes up for it with an unnecessary whale-tail tacked onto the back-end for style. Each offers more than adequate cooling for the CPU and chassis, and each of them technically has plenty of room to work inside. We’ll get more into that “technically” weasel-word.
The HP Omen 30L came to us with a fluid-cooled Intel i9-10900K CPU and a GeForce RTX 3080 GPU. The Lenovo Legion came with a more modest air-cooled Intel i7-10700 and GeForce RTX 2070 Super. Both systems (along with Dell’s Aurora R10/R11) are at least theoretically configurable to whatever performance levels you’d like, but again, COVID-19-constrained supply and demand tend to limit your options unpredictably from week to week.

Lenovo Legion Tower 5i
We broadly expect similar performance from a given CPU and GPU combination coming from any given manufacturer. But there are some other variables that impact performance—particularly the cooling. Still, in our experience, these gamer-targeted rigs are unlikely to under-specify the cooling. That means the big things we’re looking at here are the look of the system, how noisy it is, and what it’s like to work on.
Fan noise
The Legion Tower 5i is generally quieter than the Omen 30L, despite the Omen’s fluid cooler. Neither machine is loud in normal operation, but the Omen’s fans have a slight rattly undertone. The Legion’s fan noise did a much better job of fading imperceptibly into the background—I actually pressed my ear to the chassis the first time I powered it on to make sure it was booting.

Alienware Aurora R11
A full Cinebench R20 run turns the normally well-behaved Lenovo and HP rigs into raging beasts that seem likely to lift off the desk under sheer fan pressure. But both machines stay quiet until the last third of the Cinebench run and go back to—as one Ars reader described it—”wabbit-hunting quiet” a few seconds later, even while running single-threaded Cinebench. Neither machine ramped up the fan noise at all during 3DMark Time Spy tests at 1440p, which are considerably more demanding than most AAA games.
I didn’t have an Alienware Aurora R11 on hand, so I cannot compare it directly. Tom’s Guide described it as loud and hot, which I wouldn’t call either the Lenovo or HP rigs. I asked Ars Senior Commerce Editor Jeff Dunn to put his i9-10900K/RTX 3090 powered Aurora R11 through the same tests. During Time Spy, Dunn said his R11’s fan speed increased significantly. He described it as easily audible from four feet away without being “brutal.” It never went into the kind of raging beast mode that the Omen and Legion did during Cinebench R20.
By spinning up earlier and more aggressively than the Omen or Legion, the R11 manages to avoid accumulating enough thermal buildup to require emergency high speeds on the fans later. With its smaller cooling capacity, it probably doesn’t have much choice in the matter. The Omen and Legion, with considerably higher capacity, gamble that extreme thermal spikes won’t last long enough to require increased fan speed and noise. The fact that they don’t spin up until the end of a Cinebench run—and return rapidly to idle afterward—argues that they’re correct about that, too.
Users who prefer the R11’s “a little more fan now, a lot less fan later” style tuning can adjust the fan curves in either of the bigger systems to match—which would be a very good idea indeed, if you plan to use your gaming system for long-term 100 percent CPU output like protein folding, hour-long compilation jobs, etc.
The bling
-
The Omen 30L is the fanciest debutante at the ball in every category except—maybe—desktop wallpaper.
Jim Salter -
HP’s Omen 30L is a smorgasbord of disco fever—RAM, fans, the GPU, and anything that didn’t actively and vigorously defend itself got a glow-up.
Jim Salter -
Check out the LED “rope” lighting around the fluid cooler radiator, mounted at the top of the chassis.
Jim Salter -
The Legion 5i is much more subdued than the Omen 30L. The Legion icon on the front doesn’t even light up… or does it?
Jim Salter -
The Legion 5i has a saffron-tinted glass side panel, and a rather radioactive green light-up for its RTX 2070 Super GPU.
Jim Salter -
Remember how we said that Legion 5i logo didn’t glow? Turns out we were wrong. When the machine enters Windows sleep mode, that giant icon flashes bright blue, on a roughly six-second cycle. Um. #dislike.
Jim Salter -
The LED ring on the front panel—and the mildly weird overall shape—are all the bling you get in the Aurora R11.
Dell -
Unlike the HP and Lenovo gaming rigs, the Aurora R11 has no glass side panel—just a couple of hexagonal perforation clusters through its plastic shell.
Jeff Dunn
If bling is your thing, HP’s Omen 30L mid-tower is ready to be your favorite rig. HP didn’t miss a chance to glow up any individual part of this system, and the result is a gaudy but pleasing discotheque vibe that just needs you to add some bass. The HyperX RGB RAM glows its way softly through the rainbow on a loop, the chassis intake fan and Omen diamond logo on the front throw pearlescent light out into the room, the GPU announces itself with more LEDs, and even the fluid cooling system’s radiator has rope LEDs wrapped around it.
That level of ostentation isn’t to my personal taste, but the overall effect is well done. The light from the system’s various elements melds together nicely, producing a soft, cool glow that feels sci-fi-movie cool.
Next to the Omen 30L, Lenovo’s Legion 5i seems pretty restrained. The Legion 5i has a yellow-tinted glass side panel, but the only light-up component inside is a custom GeForce RTX 2080 Super GPU cap. A large Legion logo on the front of the case appears white and unlit—until the machine goes to sleep, that is. With the 5i in sleep mode, the big Legion logo flashes bright blue in a roughly six-second on/off cycle that I found both pointless and obnoxious.
I suspect that there’s a control, somewhere, to change the behavior of that LED-lit Legion logo. But it didn’t reveal itself to a casual search of the pre-installed Lenovo app in the system tray, and I didn’t burn any more time looking for it.
The Alienware Aurora R11 is the plainest system of the lot. The only light-up bling on the R11 is a slim LED trim ring on the front and an “Alienware” branding on the right side; there’s no side panel, and the entire exterior shell is plastic, available in “Dark Side of the Moon” (dark, charcoal gray) or “Lunar Light” (somewhere between pale gray and pearl). It’s also the smallest internally—the R11 is a micro-ATX system, while the other two are full-sized ATX.
