[1] The album has been regarded as "easily one of Open Mike Eagle's most enjoyable efforts" and as "feel[ing] like the culmination" to his discography.

[1] The 1990s also inspired the visual direction of the album, which references touchstones of the era such as VHS tapes and the retailer Circuit City.

[8] Component System was widely characterized by critics as featuring a looser structure and a more whimsical mood than Eagle's previous albums.

[4][3][11] Eagle's technical skill on the album was also viewed positively: critics described him as writing "tightly packed nerd raps" that were "filled with casually brilliant moments".

[10] Sonically, the album was described as featuring "sample-rich production with... nostalgic low-end",[6] and as displaying lo-fi and boom bap influences.
