Palicomp’s Phoenix i5 Quantum Slipstream combines insane processor power, upgradability and a surprisingly decent selection of components and peripherals. An Intel Core i5-2500K processor is overclocked to a staggering 4.7GHz, which explains the enormous heat sink bolted on to the CPU. It also explains the system’s characteristic sound – a rush of air that’s fairly unobtrusive but easily audible through the lightweight case.
The top PCI-E x1 slot is a little fiddly to get to, but usable. There are another two further down the ATX motherboard, but one is blocked by the graphics card. The motherboard is a Gigabyte P67A-UD4, which has an excellent range of ports and expansion slots. There are also three PCI and a spare PCI-E x16 slot, all of which are easy to get at. The board bears 4GB of fast PC3-12800 RAM and has the capacity for up to 32GB. The only two SATA3 ports are in use, but at least there are four spare SATA2 connectors. The internal layout is spacious and easily accessible, making this a good choice if you want to install lots of your own expansion cards.
At the rear of the case is a generous array of two eSATA ports and ten USB ports. Two of the latter are USB3, and there’s an unused USB3 header on the motherboard that you can use to connect a further two. At the front of the case are just two USB ports, plus headphone and mic connectors. Hardly any of the case’s internal or external drive bays are used – one 5 1/4in bay holds a DVD re-writer and a 3 1/2in internal bay houses a 1TB hard disk.
For £650, this is a well-balanced PC with plenty of power. It’s not quite as good as the Chillblast Fusion Aurora, though. However, don’t forget that you can buy it without the monitor for £575 and pair it with a better monitor for a total of around £700. If you need the fastest possible processor, this is a great choice.
