Passmark Performance Test score 6341, with improvements available in the least expensive area - Drive speed (SATA SSD out, NVMe in for a serious boost). As it is, this PC registers in the top 27% of all PCs tested by Passmark.

Price Guide: Trademe has today sold a near-identical box - smaller drives, cheaper case, no monitors - for $1050. The others with RX 5700X or RTX 2070 are $1500+.
