HP Z1 Workstation Review


This summer HP has brought on a beast of a business machine in the Z1 all-in-one Workstation , complete with an upgradable set of innards and all-in-one style. The display is a massive LED-backlit 27-inch IPS panel at 2560 x 1440 pixel resolution and...

This computer is a fabulous choice for an office in need of massive displays and Windows 7 (or Windows 8 later this year). You've got a perfectly solid build, HP has made the entire structure out of high-end components, and you'll be able to modify...

HP Z1 Workstation review


Summary: HP's Z1 Workstation is a well-designed, powerful and upgradable all-in-one PC suitable for a range of professional power users. Although not without its flaws, the Z1 is well worth considering if you want something different from the...

Large, high-quality screen, Clever flip-open design, Solid build quality, High-end components

Bulky and heavy, Awkward screen adjustment mechanism, Some inaccessible ports, No eSATA or Thunderbolt ports

HP Z1 Workstation Review: Pretty, Powerful, and Pricey, but Not Perfect


The new HP Z1 Workstation is the most attractive, most powerful, and most expensive all-in-one PC I've ever seen. And that isn't an exaggeration: This all-in-one workstation, the first of its kind, has a gorgeous 27-inch edge-to-edge glass screen,...

Very powerful ; Bright and beautiful screen

Inconvenient port placement ; No touchscreen option

The expensive Z1 all-in-one has both brains and beauty, but it also has some issues that are impossible to ignore.

HP Z1 Workstation: High-End Hardware In An All-In-One


What comes to mind when you think of an all-in-one desktop or workstation? A low-power CPU? Maybe even a mobile-oriented processor or ARM-based SoC? Integrated graphics, almost certainly. Or maybe a mobile GPU with severely limited upgrade options, at...

HP Z1 Workstation and ZR2740w Monitor Review


The Z1 is a solid workstation that is a joy to use, and a few features away from being ideal.

Easy to change components, Fast and simple to troubleshoot, Compact with many conveniences, Large display

Limited inputs and outputs, Screen glare

HP Z1 Workstation


No oops about it, HP has done it again with the introduction of the Z1 Workstation. The engineering behind the first all-in-one workstation-class computer is nothing short of amazing. Designed specifically for professionals in the graphics,...

High performance; easy to upgrade

No touchscreen capability; poor placement of back ports

Expect power and performance in a sleek, sexy, and easily accessible chassis that will make all the diehard Apple fans sit up and take notice. The Z1 Workstation is available starting at $1,899 with fully customizable options. (For benchmark results,...

HP Z1 Workstation Review


Power without the tower" indeed.

Easy to access internal components, space-saving, great screen quality, quiet performance, GPU acceleration is a big bonus

Screen can be quite glossy at times, dual HDDs need to be 2.5

HP prides itself on what they call the “Z-DNA”, which defines their workstation lineup. One aspect of this is the fact that all of HP’s workstations can be fully serviced without the need to remove a single screw. This is especially true of the Z1,...

HP Z1 Workstation


The HP Z1 merges two worlds: the all-in-one desktop and the professional workstation. Typically, an all-in-one is a space-saving and sleek consumer PC, while a workstation is a professional-grade system in a traditional tower. With the HP Z1, business...

Sleek design ; Professional-grade components ; Easy-to-access internals for an all-in-one ; Quiet operation

Rear ports are difficult to reach

Whether you view it as a remarkably sleek and slim workstation or an insanely powerful and reliable all-in-one PC, the HP Z1 is unique: it's the first 27-inch all-in-one workstation.

HP Z1 Workstation


First Look Review: Distinctive all-in-one system has it all — and it all fits inside a 27" display.

The HP Z1 is a powerful workstation, which comes at a price. Our review unit, which can only be described as fully loaded, was priced at $5,673 (including the stunning 27" display). Visit HP's web site to price a custom configuration to your exact...
