I've just declared this the best budget compact PC case, and now I'm tempted by that all white build

I've never really been the biggest case guy. With upkeep around PCs (both upgrades and general cleaning), I've always found myself in favour of something tidy and easy to hide away, rather than something to show off. That's until I had the realisation it's not quite an either-or situation back in May. Now, months later, the Thermaltake S100 TG Snow Edition takes its rightful spot as the best budget compact PC case, and boy, does it make a good argument for building that all-white build that's been on my mind ever since.

The S100 TG is what Thermaltake calls a 'micro case', which is to say it can fit Micro-ATX motherboards and smaller. You won't get all the trappings of a full tower here, but you get a smaller size in return. Despite this, it's quite a capacious case, with room for a 160 mm PSU and 330 mm GPU. In a real-life test, our Jacob found that it could house a Gigabyte GeForce RTX 5070 Ti Eagle OC Ice SFF, but not an XFX Swift RX 9070 XT.

It was not until 2019, after just finishing a degree in law and media, that they decided to throw out the last few years of education, build their PC, and start writing about gaming instead. In that time, he has covered the latest doodads, contraptions, and gismos, and loved every second of it. Hey, it’s better than writing case briefs.
