How to Build the Ultimate 3D Home Theater PC
Cutting-edge? Try bleeding-edge. Our guide to home theater reveals what components you should buy and how you should set them up
Hey, we get it. We understand that the way you watch movies and TV is different than the way we do, and that this probably differs significantly from the way your neighbors enjoy their living room and/or den. But we also understand that some fairly basic carnal desires rule our decision-making. Humongous HD screens. 3D movies. High-fidelity lossless sound. More HD recording options. Playback anywhere in the house.

At its core, the home-theater dream can be distilled as follows: We want our movies to feel as cinematic as possible. And we want to be able to record and watch as many shows as possible on the biggest-possible TV screen.
When we set about constructing this year’s home theater, we used the phrase “cutting-edge” as our guiding light. A funny thing happened on the way to cutting-edge, however. As we started identifying the components and parts and controllers and cards—many of which are being released just as you read these words—we began to realize that we were on the bleeding-edge. We’ll take that. In this story, you will find:
- What PC parts and components you should use in crafting the HTPC at the center of your home theater.
- How to capture and record four different HDTV streams at the same time using a single CableCARD device.
- What the best networking products and techniques are, as well as how they can best be used to serve TV, movies, and music within your home network.
- How to set up your system so that you can watch 3D programming and Blu-ray movies in the most cinematic style possible.
- How you can best use Windows’ built-in Media Center package to access Netflix, Hulu, and your Blu-ray content.
We’ll stop here, so that you can get into the heart of our lengthy guide. Enjoy the ride, and as always, we’d love to hear your thoughts, tips, and deepest home-theater desires at comments@maximumpc.com.
Inside Maximum PC's 3D HTPC
A unique combination of parts provides an optimum entertainment experience
In building our 3D HTPC, our two primary motivations were minimal acoustic interference and full home-theater functionality. No one wants to hear the shrill whine of a fan when Michael tells Fredo, “You broke my heart.” And if an HTPC machine can’t play a 1080p trailer, stream HD video, and play Blu-ray 3D, it’s a fail. This essentially eliminated all Atom-based configurations as well as anything using integrated graphics (at least right now). Our final 3D HTPC is slightly tall but not deep, and our InfiniTV CableCARD tuner snapped into it without any problems. Here’s the full breakdown, compliments of our awesome photography department.

Videocard
The GeForce GT 240 is one of only three GPUs that officially support Blu-ray 3D (the other two being the GTX 470 and GTX 480). The Zotac GT 240 has the distinction of also being fanless, which makes it perfect for our 3D HTPC. You should note that we are running the Zotac card in an x8 PCI-E 2.0 slot, as the passive heatsinks for the CPU and GPU could not coexist. We first considered Dremelling off a chunk of the Zotac but settled on running it in the second slot. Because x8 PCI-E 2.0 is the equivalent of x16 PCI-E 1.0, and because we are unlikely to ever run out of bandwidth, the second slot made more sense.
Power Supply
While there are external power-brick PSU options that are totally silent, they are limited to 200W, so we opted for a standard ATX PSU. Fortunately, fan noise is not an issue with Silverstone’s NightJar ST40NF, which is fanless. This doesn’t mean cooling isn’t required, however. For that, we rely on the Grandia GD05’s three 12cm fans to keep the PSU cool. Capable of producing 400 watts, the NightJar is pricey but it makes our 3D HTPC ultra-quiet. And believe it or not, it’s rated by Silverstone to run a GeForce GTX 470, to boot.
Operating System
We chose 64-bit Windows 7 Ultimate Edition as our OS, but you’d also be fine with Windows 7 Professional. One of the most surprising aspects of this iteration of Windows is the stability and feature-richness of Windows Media Center.
Hard Drive
It’s quiet, cool, and uses less power than higher-rpm drives, so it’s no surprise we tapped a Western Digital 2TB Caviar Green drive to provide storage.
Motherboard / RAM
We considered Mini-ITX and other proprietary mini mobos but ultimately settled on MicroATX for our HTPC build. This gives us a wealth of options for add-in cards and we don’t have to sacrifice any features. MSI’s 890-GX offers support for 140-watt chips (including hexa-cores), USB 3.0, and SATA 6. It also features two physical x16 PCI-E 2.0 slots and a single x1 PCI-E 1.0 along with a legacy PCI slot. For RAM, we decided that 4GB of OCZ DDR3/1333 would be more than enough.
Chassis
Silverstone’s Grandia GD05 features three nearly silent 12cm fans and can accommodate an 11-inch Radeon HD 5970.
TV Tuner
We’ve always been slightly skeptical of CableCARD products, and the initial “CableWHAT?” response we got from Comcast support did nothing to alleviate this. However, once we got our hands on a Comcast multi-stream CableCARD (achieved by simply walking into the Comcast store) and plugged it into Ceton’s brand-new InfiniTV 4 Digital Cable Tuner, we became believers. Being able to record four different channels at the same time epitomizes the notion of a power-user’s HTPC.
Soundcard
AuzenTech’s X-Fi Home Theater delivers not only best-in-class audio for our home-theater rig, but high-definition Blu-ray soundtracks, too.
CPU and Cooler
We’ve found that sub-2GHz procs don’t have the spunk to run compute-intensive chores by themselves, such as scaling video. Even though we have a discrete GPU here, we wanted to make sure we avoided the dropped frame rates a sub-par CPU can cause. With its 2.4GHz clock speed and four cores, AMD’s Athlon II X4 610E seems to be made for HTPC use. Even better, this processor is rated at 45 watts, which makes it practically ice cold when running. We paired it with a Silverstone NT01-E cooler, which can run in passive mode with up to 65-watt procs. Since our Athlon II is 45 watts, we have plenty of thermal headroom.
Optical Drive
To play Blu-ray 3D, you need a drive with a minimum read speed of 2x. Our Samsung SH-B083 combo drive meets that specification and even burns DVDs at 16x, too!
