5 HP Z1 Workstation

From £1405

Another all-in-one? Not really. The HP Z1 is a little different to most all-in-ones, first HP class this as a workstation as it comes with high-end Intel Xeon processor options, alongside Nvidia Quadro 1000M graphics for professional OpenGL applications. It's these high-end options that really help the HP Z1 stand out, even the entry-level model is built around the same impressive 27-inch IPS LED display with its startling 2560x1440 resolution, which makes it perfect for graphic professionals of all persuasions.

Unlike most all-in-ones HP has made this model entirely serviceable, so it can be opened up, upgraded or self maintained. Another slick feature is the fold-out stand, capable of positioning the screen at any angle.

The base-model only offers a Intel Core i3 2120 with 2GB of memory, which seems somewhat underwhelming for the price, however it is preinstalled with 64-bit Windows 7 Pro and comes with a reassuring three-year warranty.
