Thanx again for comments from Frank + others. Here is a revised list of parts. The probable list uses PCIe 4.0 , the alternative 3.0. The former requires a graphix card, which adds $ 300 to the total cost (all prices in CAD).
Probable : CPU : AMD : CPAMD00136 : Ryzen 7 : 5700X : 8-Core/16-Thread : $ 379 7 nm ZEN 3 Processor : Socket AM4, 4.6 GHz boost, 36 MB Cache no graphix : PCIe 4.0 Mobo : MBGIG00145 : Gigabyte : X570 Aorus elite WIFI : $ 220 dual PCIe 4.0 M.2 : Intel dual-band 802.11ac wireless front USB Type C : RGB Fusion 2.0 Graphix : VCMSI00255 : MSI : Radeon RX 6500 XT MECH 4G OC : $ 309 18 Gbps , PCIE 4.0 , DP1.4 HDMI , RX 6500 XT Mech 2X 4G OC or VCASU00335 : ASUS : Radeon RX 6500 XT OC : $ 299 PCIe 4.0, 4 GB GDDR6, HDMI 2.1, DisplayPort 1.4a, Dual Ball Fan Bearings, All-aluminum Shroud, GPU Tweak II Memory : MEKIT00523 : Kingston Fury Beast : 2 x 16 GB : DDR4 3200 MHz : $ 160 SSD : SSKIT00120 : Kingston KC3000 : 1 TB : PCIe Gen4 : NVMe M.2 R 7000 MB/s ; W 6000 MB/s : $ 190 HDD : HDSEA00016 : Seagate IronWolf : 4 TB : CMR : SATA 6 Gb/s : 5900 RPM : 64 MB Cache : 3 Yr Warranty : $ 110 Case : CSDCL00015 : Deepcool D-Shield V2 ATX : Compact Mid Tower Case : $ 60 CSDCL00019 : Deepcool E-Shield : Mid Tower Chassis, Black, Tempered Glass, 120mm Fan, Radiator Support, E-ATX/ATX/MicroATX/MiniITX : $ 60 Power : PSTHL00007 : Thermaltake Smart White : 700 W 80 PLUS Certified Power Supply : $ 80 Total cost : $ 1508 Alternative : CPU : CPAMD00131 : Ryzen 7 : 5700G : 8-core 16-thread : $ 388 Socket AM4 : 3,8 / 4,6 GHz : PCIe 3.0 ; Radeon Graphix Wreath Stealth No graphix card SSD : SSKIT00103 : Kingston : NV1 : 2 TB : NVMe M.2 : $ 185 Read: 2100 MB/s ; Write: 1700 MB/s Total cost : $ 1203 Comment : I can afford the extra $ 300 for the much greater speed of PCI 4. There are 2 possible graphix cards, others being more costly : any comments welcome ; I'm willing to consider Intel instead. -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
