lenovo K410 (57308564) Desktop PC Intel Core i7 3770(3.40GHz) 8GB DDR3 2TB HDD Capacity NVIDIA GeForce GT 620 1GB Windows 8

Pros: Cool professional case Design.
The LED power indicator is cool looking.
Good specs for price.
Quad Core 3.4-3.9

Cons: Motherboard has an issue with high power video cards.
Low wattage 280 watt power supply for a quad core.
Power LED requires special power connector not found on any modern power supplies
Non standered front panel headers/leads - hard to upgrade the motherboard.

Other Thoughts: I upgraded the power supply to a Antec Green 650 watt. Then installed a GeForce GTX 660. I got a black screen. I checked my work and even tried different power supplies -nothing worked. I tried different known good video cards and powersupplies also with no luck. I even checked the voltage output with my meter - Perfect. Only very low power (Low porformance) Video cards would POST in this system.

Lenovo has cut some corners within the motherboard, so as only lower power/performance cards will work in this system. I have heard of others online having the same issue with similar Lenovo systems.

Pros: Great operating system and extremely fast is great for gaming and every day use.

Cons: The only cons are just minor it does now have a great video card in it, don't get me wrong the one in here is good but not great also if you upgrade the card the power supply is tooo low need a new one other than that great
