Back in the day, it was common for many prebuilt systems to use custom components that couldn’t be upgraded. Non-standard form factors for power supplies and motherboards were common, meaning that you couldn’t switch these components out when you wanted to upgrade. The Lenovo Erazer X700 Gaming System is built entirely with standard components. You could strip the system down to a bare case and install all-new parts without a problem. Specifically:
- Although the system is delivered with a micro-ATX motherboard, there’s room for a full sized ATX board and 8 slots in the rear of the case.
- The 610-watt power supply has 6- and 8-pin connectors for two graphics cards, even though only a single 6-pin connector is used in the standard configuration.
- There are four open 3.5″ drive bays, two hot-swappable with a pre-wired backplane, and two open 5.25″ device bays.
- There are three open USB 2.0 connectors on the motherboard (two standard dual-port USB headers, one of which has one port used) and three open SATA ports.
- SInce the included liquid cooling system kept the overclocked (if not overvolted) CPU plenty cool, there’s probably enough thermal headroom for a 6-core CPU. You could always add another fan on the inside for a push-pull setup (you’d need a fan power splitter since there are no available fan headers.)
There is one problem: the OEM version of the GTX660 used in the Erazer X700 has 1.5GB of video memory, rather than the 2GB that retail GTX660 cards have. This presents a problem if you want to upgrade with another GTX660 in SLI, since SLI won’t work if the two cards have different amounts of VRAM. In any case, Lenovo doesn’t provide an SLI bridge with the system, so you’d have to find one of those.
You might run short of power leads when you’re expanding this system: although the power supply is rated at 610 watts, aside from the PCI-E power connectors, there’s only a single unused SATA power connector, positioned to be usable for one of the open 5.25″ bays.
I did notice one anomaly with the power supply: it’s a Lenovo model FS8003 and has an “80 Plus Gold” sticker on it:
However, this supply is listed with an “80 Plus Bronze” certification on the plugloadsolutions.com web site. It also shows the maximum wattage as 625 watts rather than 610 watts, and note that the 610 watt supply on the next line down is listed as Gold-certified.
You might have to get some power supply splitter cables, but you’ve plenty of room to expand this system.
