Hi,

I'm planning to upgrade my almost 8 year old rig and found this prebuilt system:

Case: MSI MPG Sekira 100R

PSU: be quiet! Pure Power 11 FM - 850W 80 PLUS Gold

Mainboard: Gigabyte B550 Gaming X

CPU: AMD Ryzen 5 5600X, 6x 3.70GHz

Cooler: be quiet! Pure Rock Slim 2

RAM: 16 GB DDR4 Corsair Vengeance RGB - 3200 MHz

GPU: AMD Radeon RX 6900 XT - 16GB

SSD: 1000 GB M.2 SSD WD Blue SN570

At a price of ~1460$/1499€.

What is your opinion?
