The iBuyPower P900DX
The P900DX is iBuyPower's top-of-the-line workstation system. Starting at just $3,699, our test unit is loaded with a ton of extra options, which brings the grand total to $7,816.
First of all, this thing is an absolute beast, arriving to our lab with a shipping weight of 63 lbs! The base model chassis is iBuyPower’s own Erebus GT, which is actually a custom variant of the NXZT Switch 810. The panels all the way around are NXZT's stock design, as is the interior. But the top of the case is custom. Convenient louvers are added to accommodate water cooling units for this system’s dual processors.
The rear of the P900DX is as plain as the P500X, but thankfully void of dangling cables. An extra case fan on the back helps keep hot air exhausting out of the PC, which indeed generates plenty of heat.
The P900DX can only be configured with modular power supplies, and our test unit comes equipped with the optional Thermaltake Toughpower Grand 850 W. The modular PSU definitely helps simplify cable management, and all cords get routed behind the motherboard tray. Good thing, too, because the SSI EEB form factor motherboard results in a packed enclosure.
The power button is located toward the upper-right corner of the tower, with the reset switch, headphone/mic jacks, an SD/MMC card reader, two USB 3.0, and two USB 2.0 ports hidden behind a flip-up door in the uppermost 5.25” drive bay. Overall, we like the design. Our only gripe is the position of the reset button, which is easy to press accidentally when you try to unplug a mic.
The Erebus GT is a solid case, so long as you don’t plan on actually moving the system. Pros include plenty of expansion space and room to work. Cons include a total lack of sound insulation and exhaust heat. In our lab, the P900DX was placed right around ear height, so the fans for the liquid cooling system were clearly audible, especially when the system was busy churning through a heavy workload. The exhaust from the vents was also pretty warm. It wasn't unbearable, but it could quickly get that way if you put it under a desk.
Now, let's take a closer look at the specs of these workstations, and the gauntlet of benchmarks that awaits them.
