Is this good value?

Howdy all, looking for some advice and I'm thinking this is the right place. Recently decided that I love handheld gaming but PC handhelds are expensive. I enjoy the portability of say my phone with a backbone attached and I've also recently discovered the Wonderful world of sunshine/moonlight. I was hoping to build a machine and install steam os on it as a living room rig, while also streaming from it everywhere else in the house. I'm in Canada by the way and ram/storage prices are probably worse than even the US. Happened upon a seller near me and I'm thinking he's offering a great deal so I wanted some opinions before potentially grabbing it. Please see below: Specs: AMD Ryzen 7 9800X3D 4.7 GHz 8-Core Processor SK700 AM5 Air Cooler: 7 Heatpipes CPU Cooler for AM5 Exclusive Black Single Tower PC Cooling with 120mm FDB PWM Quiet Fan & L-Rail Lock Mount Asus TUF GAMING B850M-PLUS WIFI Micro ATX AM5 Motherboard Corsair Vengeance 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory Western Digital WD_BLACK SN7100 1 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive Lian Li A3-mATX MicroATX Mini Tower Case Black/wood color Super Flower Leadex III 850W Gold Power Supply, ATX 3.1 Compatible, black 3x Arctic 120 slim case fans windows 11 home oem with key preinstalled No GPU but a buddy of mine will sell me a 9060xt 16gb for around $400 CAD. All in all, I'd pay about $2100 CAD/1500 USD. Should I second guess it or grab it as fast as possible?
