Have you looked at Corsair's AI Workstation 300 Desktop PC? [1] It's 2000-2700 EURO depending on model, and taking VAT into consideration it's comparable to the 1700-2300 USD pretax prices.
I generally agree with gp. Checkout with your link says "This item is currently on pre-order" btw. Retail mini-pcs are somehow harder to obtain than general purpose ones.
