(I've been naming/numbering my VR development machines ono's after the Ono-Sendai Cyberspace 7 cyberdecks. ono3 makes me confident that by the time I get to ono7, it should be worth its namesake.) About a year ago, I built a portable workstation in a Pelican 1430 top-loader (gallery, parts list) so I could do VR development while traveling. While a bit heavier than I would have liked (fully packed, is usually about 7.7kg, or 17lb), it's comfortably personal-item/carry-on size for air travel (even able to fit under a US domestic economy seat), and I traveled with it across 4 continents, and for tens of thousands of miles without any major issues. Long story short, it did good. That being said, with the new Vive and CB/CV1 HMDs, it's not possible to stuff them into the Pelican anymore, and truth be told, I was getting a bit tired of lugging all that weight around (the Pelican case by itself weighed 2.6kg). Phase 1 of my new build was a simple transfer job. There were a few minor issues, but overall, it was pretty painless. The spreadsheet has the specifics, but the highlights of the current build: NFC S4 Mini (#005) Intel Core i7-4790K (Devil's Canyon Haswell) Noctua NH-L9i CPU Cooler Asus ROG Maximum Impact VII 2 x 8GB Crucial Ballistix Sport DDR3 1600 Plextor M6e Series 256GB M.2 PCIe SSD GALAX GeForce GTX 970 OC HDPLEX 250W HiFI DC-ATX HP Firebird 350W Power Supply I'll have a couple detail posts, but some assembly notes: There are more than a couple things you'll want to take note from the S4 Mini assembly video. Be sure to watch it in full first. I pre-ordered before I saw any mention of HDPLEX mods - the extra predrilled hole wasn't a big deal, attaching the barrel receiver to the case with one screw was fine for me. The studs that needed to removed was a bit harder. Josh posted directions, but I still had some issues - I ended up having to remove all the nuts completely and the fastening screws to remove the aluminum fascia completely, and then rocked the studs w/ some pliers to loosen, and put some gaff on to get some grip to unscrew. It was a slightly PITA. The HDPLEX by default comes with a 6+8pin PCIe power, not a dual 6pin. Josh posted about rewiring them yourself but I ended up dropping HDPLEX a line, and they mailed me a 6+6. Awesome customer service. If you order directly from them, I bet you can request the appropriate PCIe cable in the first place. You'll need to do some major cramming for the HDPLEX wiring, but it wasn't terrible. The Galax GTX 970 OC isn't technically a mini-ITX sized card (it's a tiny bit longer), but it had no problem fitting (pic) - the only slighty weird thing is that even with it flush against w/ the insert slots in, there was a 4mm gap or so where the backplate screws were - not sure if this is normal, but I had to dig out some longer screws to secure the card. I started off with a Zalman CNPS2X and a Scythe Slip Stream 120 for cooling, but it fell a bit short for my CPU, so I switched to the Noctua NH-L9i (I'll post power and heat details next). As a point of reference, this system runs The Division beta at 1080p Ultra at 45-55fps (I'll probably end up doing a bit of GPU OC and turning down some settings to hit a solid 1080p60 if Nvidia driver updates don't fix things). Feel free to add me as a friend if you plan on playing: randomfoo2 I'll be moving onto step 2, which is using this as part of a Backpack Rig (for completely untethered VR usage) soon... I finally published a full write-up of the backpack setup on my blog. I was meaning to get some non-janky mounting done for it, but never got around to it, so gaff tape it is, but you get the idea.
