Welcome to my computing page. Here, I give various advice associated with personal computers mods, home network and Raspberry Pi and similar projects.

My interest in computing dates a long time back, but even now, I still proudly built and own a desktop computer I use almost daily, as well as my own server. Over the years since upgrading a Pentium 133 to an AMD K6-II 300 and adding an 800MB hard drive, I've probably built 20 or more PCs for myself, family and helped friends. As of now though, I own:

1. A PC in the small bedroom (office) room for working and some gaming - Mini ITX, AMD Ryzen 9 5900x, AMD RX 6700XT, 2x 1TB NVMe SSDs, 32GB RAM, Linux Mint 21
2. A router and server handling my Internet and hosting my data - Mini ITX, Core i7 10700, 1TB NVMe SSD, 512GB NVMe SSD, 2x 1TB SSDs, 1x 2TB backup drive, 32GB RAM, Linux Ubuntu 22.04
3. Wife's PC - Mini ITX, Core i5-9600, 1TB SSD, Blu Ray drive, 16GB RAM, Windows 11
4. A PC in the bedroom room for watching online content - Mini ITX (again), Core i5 2390T, 256GB SSD, 8GB RAM, LibreElec
5. A second server handling VMs - Mini ITX (again!), Core i7 3770S, 512GB SATA SSD, 500GB backup drive, 16GB RAM, Linux Ubuntu 20.04

And then there were laptops, which I've owned many since my first second hand Toshiba Tecra 700CDT I got late 1999. I hardly use laptops of my own now though so I currently have an old Lenovo Flex 2-14 (FHD touch, Core i5-4210U, 16GB RAM, 120GB SSD, Linux Mint 21) and a Lenovo IdeaPad 120S-11 (Celeron, 4GB RAM, Linux Mint 21).

Since 2017, I used Linux Mint on my desktop, and now use it everywhere and recommend it over Windows® these days, but I do still keep a Windows 11 VM for that occasional need.

Below are my projects old and new, however my blog page also contains smaller posts with info on PC upgrades, Laptop upgrades, Linux and Windows® tips.
