Deal for Geeks: Okdo (Radxa) ROCK 5 Model B 8 GB Single Board Computer

This seems like a good deal for an 8GB SBC when the 4GB version is £9 more expensive and the 16GB is £195. At £107.12 ex VAT I think this is mispriced and the cheapest I could find it elsewhere was £157.
This is a raspberry Pi 5 rival and an rpi5 is £168 for the 8GB version. This has 4 more cpu cores, it has built-in M.2 2280 pcie 3.0 x4, an M.2 E-key slot for wifi etc cards, an eMMC socket and a 2.5GbE LAN port. Please note its a rival so not everything that works with an rpi5 will necessarily work with this.
Pricing up for an rpi5 8GB (£168) with M.2 HAT (£15), 27W rpi5 PSU (£15) and a case that can fit the rpi5HAT (£15) comes out at £213. The equivalent pricing for the Rock 5B comes to £163 using:

And for that you get 4 more arm cores, 3 extra pcie 3.0 lanes going to your M.2 SSD, the eMMC socket and a 2.5GbE network for £5 less than just a base rpi5 8GB board.
You will need some technical expertise to get this running so its not necessarily for newbies though could still be fun.
