Any recommendations for buying a barebones PC? I dont need anything high end, so i3 or below is good enough for what I need. I have SSD’s to install.

Years ago I use to get mine from either ebuyer or novatech, any others worth a look?

Use https://uk.pcpartpicker.com/list/ to find parts and compare prices.

ebuyer, novatech, scan, overclockers, amazon, ccl are all good options.

The various Intel NUC barebones things are very good. Easy to fit bits to and generally ‘just work’…

Have a look here

Scan have an MSI Pentium N4000 for £120. I used the Gigabyte Brix version similar and it was perfectly fine for web and office.
