Cheapest G5 in Europe I could find was 180 EUR, but sold out. And on amazon.de it's 280 EUR.
Also, the N97 has better performance than the N100, but the power consumption is higher. For me its a plus as it's more powerful than the usual N100 mini PC's while much smaller and fan noise is quite low (for now at least...). Not really intended for high workloads and 24/7 anyway. More like a backpack PC.

GMKtec sells on AliExpress if you don't mind going that route:
