Sennheiser has expanded its gaming headset lineup with four new sets. There’s the flagship Sennheiser PC 360, the surround sound PC 333D and PC 163D, and the PC 330 G4ME.

These should make your games sound pretty awesome. The flagship PC 360s have been available overseas for some time, but now they’re arriving in the U.S. for $299. They feature Sennheiser Open-Aire speaker technology, sport a volume control on the right ear cup, and the mic can be muted just by lifting it up. These should make gaming easier on the ears, while not hitting the wallet too hard.

Over the years, I have laid eyes on some strange casemods and have seen more than one machine that was submerged in oil. A new casemod has surfaced that has a Bioshock theme. The builder uses an aquarium to put his new HTPC under four gallons of mineral oil.

The mineral oil is normally used as a laxative for horses apparently. The mainboard and PSU are mounted to a clear plastic sheet and placed into the aquarium. The only hardware part not under the oil is the HDD. The maker rounded the design out with a bubble filter, gravel and a few other things.

FF fans have another piece of gear that they will need to buy. This official PC controller from Sunflex will have you playing the latest Final fantasy in style. It’s a snow white controller, very much like the Dual Shock standard that most PC gamepad makers use.

Though those hand grips are really long. For something called Final Fantasy, these games are never final. Aren’t we up to like 14 now? Should be called unfinal fantasy. The fantasy that never ends.

We have seen gaming machines before that cram processors aimed at the server market inside for higher performance. We have also seen those machines get overclocked CPUs for even better performance. What we haven’t seen is a machine that rolls so much gaming win into one package like the new Origin gaming rig does.

The machine is called The Big O and it is an absolute beast of a computer. The machine has dual 6-core Intel Xeon X5860 CPUs that are overclocked to 4.3GHz. The machine supports ECC memory and up to 24GB of Corsair RAM can be added. The machine can also be fitted with four EVGA GTX 480 FTW video cards in SLI.

A few companies track PC shipments around the globe including iSuppli. In July, iSuppli offered up the numbers for Q1 2010 and Acer overtook Dell for the second place in the global PC shipment list.

The numbers for Q2 are out and Dell has recaptured that second spot. Dell shipped 10.5 million PCs for 12.8% of the market. Acer shipped 10.1 million PCs for 12.4% of the market. Acer had negative 6.2% growth for the quarter while Dell had negative 1.2% growth thanks to its desktop and server shipments.

Computer cases can be dirt-cheap and fall apart easily or they can cost more than some pre-built computers do to purchase. The difference is how they look on the outside and how they perform on the inside. Cooler Master has some of those crazy expensive cases and it has some cheap offerings like the new HAF 912.

The HAF 912 will ship on September 14 for $59.99 making it one of the cheaper cases Cooler Master offers. For that much money you get a mid-tower case measuring 9.1″ x 18.9″ x 19.5″ and mode from SECC and plastic.

With seemingly every manufacturer introducing new tablets, it’s no surprise that Fujitsu has something to offer too. The company has unveiled its latest 10-inch mini notebook, called the Lifebook T580.

It features a swivel display, so that the device can be converted into a tablet with multi-touch display. No info on price yet, but other specs include: Up to Intel Core i5 processor, 3G, GPS, Windows 7 Professional, Ambient light sensor and up to 8 hours of battery life.

The folks over at Commodore USA are ready to bring the old school and slam it down on your desktop. The company has announced a new line-up of computers that resemble the original Commodore computers from back in the day.

The best one has to be the one shown above, which is apparently a completely new design, inspired by the original Commodore. Inside this Commodore P64 you’ll find an 2.66 GHz Intel Core I7 processor, NVIDIA GeForce GT 330M with 512 MB, 2 TB hard drive, 4GB DDR3 SDRAM, and a BLU RAY drive.

BitFenix isn’t a company I have heard of before seeing its awesome Colossus case hit the market this week. The new Colossus case looking like something you would run across in an Egyptian pyramid on Star Gate.

The chassis is a full ATX unit that has tons of space and supports ATX and larger mainboards. It has a single external 5.25″ drive bay and four internal bays of the same size. It also has seven 2.5″ or 3.5″ internal bays and a robust cooling system using 230mm fans.

Lian Li has announced another new computer case for people that want a small computer. The new case is called the PC-Q11 and it looks like it would make a nice little HTPC case in the living room or desktop for a cramped office.

The case comes in four different colors including red, silver, black, and piano white. The case measures 200mm x 326mm x 260mm and weighs 2.42kg. Supported mainboards include Mini ITX and mini DTX. The case is made from 1.5mm aluminum panels and has various features to reduce vibration and make the chassis quiet.

MSI has introduced the first high performance 3D all-in-one machine ever. The Wind Top AE2420 comes with a full HD 3D multi-touch display, and a 120Hz high scanning frequency LED panel. When used with the bundled MSI3D Infinity shutter glasses, you should have a great 3D viewing experience, without any blurred 3D images or other problems.

Some other specs include Intel Core i5 and i7 processors, an ATI Mobility Radeon HD5730 discrete graphics chip with DirectX 11 support, USB 3.0 and MSI Premium Sound Technology.

At last Batman fans, the sequel to the popular Batman Arkham Asylum has just been announced and it will be called Batman Arkham City. It will be available for the PlayStation 3, Xbox 360 and PC in the fall of 2011. The game is being developed by Rocksteady Studios, Warner Bros Interactive and DC entertainment, and it will be set in Gotham’s new maximum security prison.

With the new Arkham in the city it should make for some interesting game scenarios, allowing even more characters to show up, so that you can bring them down.

The Chip concept computer looks pretty hot. Sort of a desktop computer, notebook, and a tablet computer all together. This concept design has a removable display that can be converted into a tablet, while the hinged keyboard can be accessed when the display is docked.

It goes by the name“the Chip”. It’s a great design. Functional and futuristic. Women wouldn’t complain about ugly PCs at all if they all looked like this one.
