FOURTRESS - rugged, strong and fast!The FOURTRESS is a hardwearing, ultra-compact, aluminium-cased Raspberry Pi 4 system running RISC OS, and utilising the latest in m.2 solid state drive technology, giving it a storage performance boost over a standard Raspberry Pi with SD card, and offers performance in the range of some of the most expensive RISC OS systems on the market today.The Fourtress combines an aluminium case, which also acts as a cooling system for the machine, incorporating both an active fan and utilising the case itself as a cover-all heatsink, to dissipate heat from the system with ease. This allows for easy overclocking of the system without concerns for overheating.With it’s modern, angular looks and integrated storage, the Fourtress will make your make your system look like the contemporary machine that it is. An eye catcher it certainly is!Even though it’s a budget system, it’s still a very capable workhorse with the following specifications:Processor Speed: 1.5Ghz (overclockable up to 2.2GHz)Memory: 2GB/4GB/8GBStorage: 128/256GB fast m.2 state of the art NVMe or SATA storage Networking: Gigabit Ethernet port and optional WIFIUSB ports:3 externalAudio/Video:3.5mm Audio, audio over HDMITwin full sized HDMI portsUp to 3840x2160 HDMI graphicsSD Card: 32GB Class 10 for OS, back up and storageOS and Software:RISC OS 5.28 plus nearly 2GB of RISC OS Software as standardOTA OS upgrades with rollback facilitiesPlease visit our dedicated PiHard website for further details and to buy!

Upgrade your existing system to a FOURtressIf you already own a Pi 4 in a standard plastic case (or no case at all!), we can upgrade your system to one of our FOURtress systems, for a much reduced price. Rather than a trade in scheme, we incorporate your existing hardware into our system, including installing EDOS on the system at a configuration to suit you.When installed in our FOURtress system, the Operating Systems can be safely run at 2.147GHz without the risk of overheating. We can even install EDOS, our RISC OS and Linux Easy Dual Operating System. Using EDOS, your FOURtress can use both RISC OS and Linux, with the Linux-based Raspberry Pi OS making the best use of a solid state drive over a high speed USB 3 connection. Sadly, it’s so fast, you may never see the Raspberry Pi splash screen.Please see the EDOS page for an overview of EDOS, and contact us for details.
